NAME
aberrator
USAGE
aberrator infile=<filename>
DESCRIPTION
This tool applies velocity aberration adjustments to attitude files.
aberrator modifies the ATTITUDE extension of the input file. It saves a copy of the original POINTING column in POINTING_INERTIAL and sets the values in the POINTING column to the apparent RA, Dec, and roll corresponding to the inertial attitude. It then recalculates the quaternion (QPARAM column) to match POINTING.
PARAMETERS
- infile [filename]
- Name of attitude file to adjust.
- orbfile [filename]
- Name of satellite orbit file. This file is only used if the satvel parameter is true.
- alignfile [filename]
- Calibration file giving conversion from spacecraft body frame to attitude library convention.
- earthvel = yes [boolean]
- Include earth about sun velocity in adjustment.
- satvel = yes [boolean]
- Include satellite about earth velocity in adjustment. The velocity information is taken from the orbfile parameter.
- (history = yes) [boolean]
- Write parameter history?
- (chatter = 1) [enumerated integer]
- Standard HEAdas chatter parameter.
EXAMPLES
The following example illustrates running aberrator
specifying the parameters on the command line
aberrator infile=obssat.fits alignfile=align.fits \
earthvel=yes satvel=no orbfile=NONE chatter=3
