The following are the module parameters used by CASPER.  These parameters are saved
to the CASPER Output File.  Not all parameters are used by every module.

IMPORTANT NOTE: The parameter names listed below and saved in the CASPER Output File do not necessarily correspond one-to-one with project-approved Cassini module parameters.  The CASPER Request Working File (RWF) outputs the actual module parameter names and values for those modules implemented in CASPER which have been designed by the Cassini ground system.  Some of the parameters listed below are used for multiple purposes, depending on the module.
 

• XS, YS, ZS: The scan angle around the X, Y, or Z spacecraft axis, in radians.
• DXS, DYS, DZS: The rate of turn around the X, Y, or Z spacecraft axis, in rad/s, for turns through the angles XS, YS, and ZS, respectively.
• XR, YR, ZR: The reposition angle around the X, Y, or Z spacecraft axis, in radians.
• DXR, DYR, DZR: The rate of turn around the X, Y, or Z spacecraft axis, in rad/s, during a reposition turn, through the angle XR, YR, and ZR, respectively.
• XF, YF, ZF:  The flyback angle around the X, Y, or Z spacecraft axis, in radians.
• DXF, DYF, DZF:  The rate of turn around the X, Y, or Z spacecraft axis, in rad/s, during a flyback turn, through the angle XF, YF, and ZF, respectively.
• XA, YA, ZA:  The angular accelerations around the X, Y, or Z spacecraft axis, in rad/s, respectively.
• XOFFSET, YOFFSET, ZOFFSET:  The angular offsets around the X, Y, or Z spacecraft axis respectively, in radians, from the primary target to some specified reference point within the module.  The reference point is module dependent, but is typically the first pointing within the module.  For example, for a GENMOSA of Saturn, these offset angles give the turns around each axis necessary to get from pointing the spacecraft -Y axis at Saturn center to the first pointing within the GENMOSA.
• START_ANGLE:  A supplemental angular offset, in radians, that is used in some modules.  In NADMAP, for example, this is the offset angle from the target body North limb that the initial North-South scan begins.
• RA, DEC:  The right ascension and declination of the target reference for the body.  This is the direction from which the X, Y, and ZOFFSET turns are made to get to the beginning of a module.  This can be used as the primary inertial vector for purposes of communicating with tools that deal with Cassini's Inertial Vector Propagation algorithms.
• RA2, DEC2:  The right ascension and declination of the secondary spacecraft vector at the start of a module.  This direction is determined by the twist, and can be used as a secondary inertial vector for purposes of communicating with tools that deal with Cassini's Inertial Vector Propagation algorithms.
• POINTING_AXIS:  The CASPER Instrument ID Code for the instrument that is doing the pointing within the module.  This can be used as the primary body vector for purposes of communicating with tools that deal with Cassini's Inertial Vector Propagation algorithms.  A value of -99 indicates that this vector was not defined during the creation of the module.
• SECONDARY_AXIS:  The CASPER Instrument ID Code for the spacecraft vector that is pointing in the direction of RA2, DEC2.  This can be used as the secondary body vector for purposes of communicating with tools that deal with Cassini's Inertial Vector Propagation algorithms.  A value of -99 indicates that this vector was not defined during the creation of the module.
• DT:  The dwell time (seconds).  This is the time that the spacecraft stays at a certain inertial attitude for modules other than GENMOSP and NADMAP.
• PT:  The pause time (seconds).  This is the time that the spacecraft stays at a certain inertial attitude for the GENMOSP and NADMAP modules.
• NP:  The number of pauses in a single scan of a GENMOSP or the GENMOSP portion of a NADMAP module.
• PI:  The fractional interval of pauses in a single scan of a GENMOSP or GENMOSP portion of a NADMAP module, following the first pause.
• PL:  The location of the first pause in a GENMOSP or GENMOSP portion of a NADMAP module, expressed as a fraction of a complete scan.  The location of pause j is therefore PL+(j-1)*PI.
• M:  The number of footprints, or false footprints, in a scan.  This is the number of times that the spacecraft stops for a period of DT during a scan in the case of footprints, or the number of times that CASPER visualizes the instantaneous attitude of the spacecraft during a continuous scan in the case of false footprints.
• NS:  The number of scans.
• TWIST:  The user-specified twist angle around the pointing boresight.
• STARTET:  The ET (ephemeris time - seconds past J2000) at the beginning of a module.
• STARTUTC:  The UTC (coordinated Universal time) corresponding to STARTET.
• NAME:  A mnemonic name for the module, such as GENMOSA or ORSOCC.
• ART_START_RANGE: User input value (in degrees) for the beginning of articulation.  The default for the ART_START_RANGE and ART_END_RANGE is the maximum degrees a particular instrument FOV may articulate.
• ART_END_RANGE:  User input value (degrees) for the end of articulation.  The default for the ART_START_RANGE and ART_END_RANGE is the maximum degrees a particular instrument FOV may articulate.
• ART_BEGIN:  User may specify the position of the articulation axis.  This is only for CDA.
• ART_RATE:  Each instrument articulates at a different rate.  MIMI LEMMS1 and MIMI LEMMS2 can specify the ART_RATE, although for now, the rate is fixed at 4.16 degrees/second.
• ART_TIME:  When the user inputs a start and stop range, the time it will take to do that particular articulation will be computed and stored in ART_TIME.  The default is set to allow a particular instrument to articulate its full range as specified by the ART_START_RANGE and ART_END_RANGE values.  Note: This parameter is not saved in the CASPER Output File.
• AVAIL_TIME:  User specifies duration of articulation available.  Not dependent on the ART_START_RANGE, ART_STOP_RANGE, or ART_RATE.
