Description:
This routine converts a list of apparent RA,Decs for one date into apparent coordinates at
another. To do this it calls SLA_MAPPA and SLA_AMPQK to convert the input coordinates into mean
coordinates for a J2000.0 equinox, then SLA_MAPPA and SLA_MAPQKZ to convert the mean
coordinates into apparent on the output date.
Invocation
CALL SCULIB_STANDARD_APPARENT (N,
RA_APP, DEC_APP, IN_MJD, OUT_MJD, STATUS)
Arguments
N = INTEGER (Given)
number of
positions to be converted
RA_APP (N) = DOUBLE PRECISION (Given and returned)
apparent RA
(radians)
DEC_APP (N) = DOUBLE PRECISION (Given and returned)
apparent Dec (radians)
IN_MJD = DOUBLE PRECISION (Given)
date of input coordinates (modified Julian day)
OUT_MJD = DOUBLE PRECISION (Given)
date of output coordinates (modified Julian
day)
STATUS = INTEGER (Given and returned)
global status
