palMapqk palMapqk - Quick mean to apparent place

Description:
Quick mean to apparent place: transform a star RA,Dec from mean place to geocentric apparent place, given the star-independent parameters.

Use of this routine is appropriate when efficiency is important and where many star positions, all referred to the same equator and equinox, are to be transformed for one epoch. The star-independent parameters can be obtained by calling the palMappa routine.

If the parallax and proper motions are zero the palMapqkz routine can be used instead.


Invocation:
void palMapqk ( double rm, double dm, double pr, double pd, double px, double rv, double amprms[21], double $*$ra, double $*$da );

Arguments:

rm = double (Given)
Mean RA (radians)
dm = double (Given)
Mean declination (radians)
pr = double (Given)
RA proper motion, changes per Julian year (radians)
pd = double (Given)
Dec proper motion, changes per Julian year (radians)
px = double (Given)
Parallax (arcsec)
rv = double (Given)
Radial velocity (km/s, $+$ve if receding)
amprms = double [21] (Given)
Star-independent mean-to-apparent parameters (see palMappa).
ra = double $*$ (Returned)
Apparent RA (radians)
dec = double $*$ (Returned)
Apparent dec (radians)
