Description:
This routine takes the apparent RA,Dec as input and converts them to
the position in a specified output coordinate system. Allowed OUTPUT_COORDS are
AZ, RJ, RB, GA, EQ. This is the reverse of SCULIB_CALC_APPARENT
Invocation
CALL
SCULIB_APPARENT_2_MP(RA_APP, DEC_APP, OUT_COORDS, LST, MJD, LAT_OBS, LONG, LAT, STATUS
)
Arguments
RA_APP = DOUBLE PRECISION (Given)
Apparent RA of point at date (radians)
