File: TORUS1:[GLL_RAW.INFO]PHASE2_FPNT.DOC also see: DISKH:[GLLSEQ.LIB]ORBITAL_FIXED_PAT_TABLES.FPN *************************************************************** * This is draft of the set of DMLs for the Fixed Pattern Noise * Table for the G1 torus and Jupiter observations * Edited Nov 18,94 KES. * With add'l Jupiter table input from Ian,Edited Nov 21,94 KES * With add'l All-purpose table input from Ian, Nov 22,94 KES * * Add'l updates for changes in Neil's s/w= 1) all values are * now 2*accumulator value, 2) there is no longer a FPN * ID value in location 125, 3) there MUST be a ZERO value * in location 126 and 4) location 127 must be 2 times the * number of active accumulators. Feb 24,1995-kes * JPL testing revealed an error in the AURORA FPN. Pixel 92 & 93 * were 3D when they should have been 3E. May 1995 - JG * * Pixels are labeled from 0 to 127. A value in a location * assigns a "superpixel" reference number; several locs * with the same superpixel value indicates these pixels * will be summed into the same superpixel value. It is also * appropriate to call a superpixel an accumulator. Within * the Phase II instr. s/w, the micro reads the accumulator * number from the even location and uses it as a micro address * in which it accumulates the pixel-pair photons for that * even-odd pair. 126 must be zero because the location is * used. The values being two times their pixel-pair value * saves micro multiplication time in calculating the address. * * These FPN sets assume 24 sectors and therefore 45 pixels * If any new FPN tables are constructed containing MORE THAN 45 pixels * then it is IMPERATIVE that a 24EUV command using only one sector * be used before the new FPN is loaded. (It would be followed by * the FPN load, a new 24EUV command and a 24CLR cmd.) If this is * not done then the uP may overwrite itself. ALWAYS load a new FPN * followed by the new 24EUV command. 23-Aug,95 -KES * * The 24EUV Phase II commands are still TBD; the format is: * EUVCMD,NORM,COUNT,gain=3,start_angle,CRUISE,scans_per_sector,num_sectors * * A preliminary J0-G1 cmd is, as an example, * EUVCMD,NORM,COUNT,03,58,CRUISE,1,18 * to give 88 (dec, 58hex)= Starting Angle, 1 scan/sector, and 24d sectors * * (orig. cruise cmd: EUVCMD,NORM,COUNT,03,01,CRUISE,19,23) * * (Footnote on counting nomenclature. EUV has a 128 byte buffer * for the FPN table. The buffer is assigned usage beginning at * location zero; the first pixel to be counted occurs at FPN * number zero. The pixel channels are also numbered from 0-127. * Phase II assumes a zero value indicates a "don't use". * *************************************************************** +++++++++++++++++++++++++++Below are the corrected tables++++++++++++++ For TORUS observations: 24DML,0F00, pixels 02,02,02,02,04,04,04,04,06,06, 0 to 9 06,06,08,08,08,08,0A,0A,0C,0C, 10 to 19 0E,0E,10,10,12,12,14,14,16,16, 20 to 29 18,18,1A,1A,1C,1C,1E,1E,20,20, 30 to 39 22,22,24,24,26,26,28,28,2A,2A, 40 to 49 2C,2C,2E,2E,30,30,32,32,32,32, 50 to 59 34,34,36,36 60 to 64 24DML,0F40, 36,36,38,38,38,38, 64 to 69 3A,3A,3A,3A,3C,3C,3C,3C,3E,3E, 70 to 79 3E,3E,40,40,40,40,42,42,42,42, 80 to 89 44,44,44,44,46,46,48,48,48,48, 90 to 99 4A,4A,4A,4A,4C,4C,4C,4C,4E,4E, 100 to 109 50,50,52,52,54,54,56,56,56,56, 110 to 119 58,58,58,58,5A,5A,00,5A 120 to 127 For Jupiter AURORA AND AIRGLOW observations: 24DML,0F00, pixels 02,02,02,02,04,04,06,06,08,08, 0 to 9 08,08,0A,0A,0A,0A,0C,0C,0C,0C, 10 to 19 0E,0E,0E,0E,10,10,10,10,12,12, 20 to 29 12,12,14,14,14,14,16,16,16,16, 30 to 39 18,18,18,18,1A,1A,1A,1A,1C,1C, 40 to 49 1C,1C,1E,1E,1E,1E,20,20,20,20, 50 to 59 22,22,22,22 60 to 63 24DML,0F40, 24,24,26,26,28,28, 64 to 69 2A,2A,2C,2C,2E,2E,2E,2E,30,30, 70 to 79 32,32,34,34,36,36,38,38,3A,3A, 80 to 89 3C,3C,3E,3E,40,40,42,42,44,44, 90 to 99 46,46,46,46,48,48,48,48,4A,4A, 100 to 109 4C,4C,4E,4E,50,50,52,52,54,54, 110 to 119 56,56,58,58,5A,5A,00,5A 120 to 127 =========================================================================== For ALL-PURPOSE observations (when you cannot change tables): 24DML,0F00, pixels 02,02,02,02,04,04,04,04,06,06, 0 to 9 06,06,08,08,08,08,0A,0A,0A,0A, 10 to 19 0C,0C,0E,0E,10,10,12,12,14,14, 20 to 29 16,16,18,18,1A,1A,1C,1C,1E,1E, 30 to 39 20,20,20,20,22,22,24,24,26,26, 40 to 49 28,28,2A,2A,2A,2A,2C,2C,2C,2C, 50 to 59 2E,2E,2E,2E 60 to 64 24DML,0F40, 30,30,30,30,32,32, 64 to 69 32,32,34,34,34,34,36,36,38,38, 70 to 79 3A,3A,3C,3C,3E,3E,3E,3E,40,40, 80 to 89 40,40,42,42,42,42,44,44,44,44, 90 to 99 46,46,46,46,48,48,48,48,4A,4A, 100 to 109 4C,4C,4E,4E,50,50,52,52,54,54, 110 to 119 56,56,58,58,5A,5A,00,5A 120 to 127
