Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.

University of Colorado at Boulder. Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.

University of Colorado at Boulder. Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.

University of Colorado at Boulder. Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.

Physics (LASP) at the University of Colorado at Boulder. Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.

University of Colorado at Boulder. Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.

Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.

Refer to the Galileo UVS/EUV instrument paper 'Galileo Ultraviolet Spectrometer Experiment', Vol 60, Space Science Reviews, pages 503-530, by C.W. Hord et al, for hardware and calibration information and to the EUV Instrument template for a description of the Phase 1 (P1) cruise period format. P1 is a memory read out (MRO) data acquisition method wherein the EUV internal buffer is 'dumped' to the ground using the main computer (CDS) microprocessor memory readout function. The analysis of some of these raw data has been published in Ajello,J. M, W. R. Pryor, C. A. Barth, C. W. Hord, K. E. Simmons, Solar Wind Latitude Variations and Multiple Scattering from Galileo Interplanetary Lyman-a Observations, Advances in Space Research, Vol 13, No6, pp(6)37-(6)40, 1993 and the paper Ajello, Joseph M., W.R. Pryor, C.A. Barth, C.W. Hord, A.I.F. Stewart, K.E. Simmons, D.T.Hall, Observations of Interplanetary Lyman-a with the Galileo Ultraviolet Spectrometer: Multiple Scattering effects at Solar Maximum, Astronomy and Astrophysics, 289,283-303,1994. The data contained in the file were obtained by the EUV instrument, using the EUV P1 MRO mode, during the Pre-Jupiter, Cruise (VEEGA) mission operations phase. Check the commanded configuration in the flight sequence for the most accurate understanding of these data. Calibration to physical units has not been made; the data are in units of 'raw counts per time'. The commanded instrument summation period, number of sky sectors and number of detector pixels summed are given in the EUV command. The EUV integration time and sampling of the grating positions by use of a 'Fixed Pattern Noise Table' (FPNT) are described in the instrument template. A diagram of the file and record structure is shown below: | 2 blank lines | |--------------------| 3 | S | EUV INTERNAL BUFFER |--------------------| . 4 | S | . |--------------------| . 5 | S | . |--------------------| . . . . repeats . . . |--------------------| . 99 | S | EUV INTERNAL BUFFER |--------------------| 107 |********************| 108 | H1 | TIME TAGS FOR THIS BUFFER DUMP . . . 115 |* | 116 | H2 | TIME TAGS FOR PREVIOUS BUFFER DUMP . . . 122 | H2 | 123 |* | 124 | H3 | TIME OF LAST Z-AXIS POSITIONING 125 |* | 126 |Comments: | . . . ij |# | where S = 1520 bytes in records of 16 2-byte, Hex values containing the internal buffer dump, including engineering; H1 is the header values for the current dump; H2 is the header values for the previous dump; H3 is the time of the most current z-axis positioning (SCITURN); and Comments are any number of records of related notes followed by a record with the '#' character in the initial position. The hex data value is LSbyte first of the two. Records 1 to 106 are the telemetered data buffer records. The next 16 bytes are the Engineering values. The final 8 records contain a copy of the Fixed Pattern Noise Table, FPNT. The matrixed configuration of the data records is described below. The exact definition of the time values in the header are further described in the Galileo document 625-610. The time tags given in the headers refer to the time of the readout of the first byte of the memory read out; integration continues in the internal buffer while the dump progresses through the buffer. The exact amount of time the dump takes depends on the downlink data rate (given in the header) but is irrelevant to the summation period except in knowing the amount of 'smear' due to the time to read out all locations. Simply, the EUV samples areas of the sky, on each revolution, based on the command and the instrument integration time. The fixed buffer size is divided into sky-sectors by pixels. The detector pixels are not summed in P1 so individual pixels must be selected; a table defining the pixels is called the Fixed Pattern Noise Table and is loaded to the microprocessor each time the EUV is powered-On for the data taking. The FPNT is therefore available in the command sequence. For the P1 mission phase, there is one commonly used table: CRUISE; the Jupiter approach JA load used a different map which contained all the pixels and only five sectors. The ribbon of sky sampled is dependent on the Z-axis orientation; this knowledge is also available in the commanded sequence. A file MRO_INFO.DAT is associated with the EUV RDR files and contains a summary of Z-axis information. The data matrix is structured by sky sectors and detector pixels. It is read out so that the order of the matrix is: 1st value=(sector 0, lowest pixel sum), 2nd value=(sector 0, next pixel sum) so that all the pixels in one sector are read out before the next sector's pixels are placed into the downlink stream. The engineering values are not summed but are true, current values. Some command information is given in the engineering data embedded in the housekeeping portion of the record. The order of enginnering byte values is: 0=empty-byte, 1=starting angle, 2=Mode/HV, 3=number of scans/sector, 4=number of sectors, 5-7=instrument maintained RIM count, 8=instrument maintained minor frame (MOD91) clock, 9=instrument maintained RTI (MOD10) clock, 10-11=instrument maintained delta Theta (per RTI), 12-13=instrument maintained Theta, 14-15=scratch pad. A [35 sector * 21 wavelength] FPNT matrix was used to obtain these data. The raw dump described above is followed by a one record ASCII delimiter containing the characters '*'. This delimeter record is followed by time tag, data rate, MRO date information regarding this data dump and the same tags for the most recent, previous dump. (This information is added by the EUV team after ground receipt.) The data dumps therefore represent intensity over a summation period defined by the frequency of memory dumps. These header values therefore supply the summation duration by supplying the memory dump event times. The format of the header information is: *********************************************** This file name :EUV1325096_42.MRO Date of MRO :23-APR-1992 Commanded Start of MRO (SCLK) :01325096:42 Commanded Start of MRO (SCE) :92-114/19:38:17 OWLT(mm:ss) at 114/00:00 SCE :22:03 OWLT(mm:ss) at 115/00:00 SCE :21:57 Data Rate (1200,40)bps :10 * Previous MRO file name :START TIME Date of MRO :16-APR-1992 Commanded Start of MRO (SCLK) :01315034:28 Commanded Start of MRO (SCE) :92-107/18:04:20 OWLT(mm:ss) 107/00:00 SCE :22:44 OWLT(mm:ss) 108/00:00 SCE :22:38 Data Rate (1200,40)bps :10 * MOST RECENT SCITURN ERT UTC :92-104/21:19 * Comments: # Note that the 'Comments' section can contain any number of lines and is followed with the line containing the '#' and End-of-File.
