Methods Documentation

apply_configuration()

Update telescope information with FITS header information.

Updates the information by taking the following keywords from the FITS header:

TELESCOP - The observatory name (str)
TELVPA - The boresight position angle (degrees)
LASTREW - The UTC time of last telescope rewind (str)
FOCUS_ST - The focus T value at start (um)
FOCUS_EN - The focus T value at end (um)
TELEL - The telescope elevation in cavity (degrees)
TELXEL - The telescope cross elevation in cavity (degrees)
TELLOS - The telescope line-of-sight angle in cavity (degrees)
TSC-STAT - The TASCU system status at end (str)
FBC-STAT - The flexible body compensation system status at end (str)
ZA_START - The zenith angle at start (degrees)
ZA_END - The zenith angle at end (degrees)
TRACMODE - The SOFIA tracking mode (str)
TRACERR - Whether there was a tracking error in the scan (bool)
TELCONF - The telescope configuration (str)
EQUINOX - The coordinate epoch (year)
TELEQUI - The boresight epoch (year)
TELRA - The boresight RA (hourangle)
TELDEC - The boresight DEC (degrees)
OBSRA - The requested RA (hourangle)
OBSDEC - The requested DEC (degrees)
