palFk524 palFk524 - Convert J2000.0 FK5 star data to B1950.0 FK4

Description:
This function converts stars from the IAU 1976, FK5, Fricke system, to the Bessel-Newcomb, FK4 system. The precepts of Smith et al (Ref 1) are followed, using the implementation by Yallop et al (Ref 2) of a matrix method due to Standish. Kinoshita's development of Andoyer's post-Newcomb precession is used. The numerical constants from Seidelmann et al (Ref 3) are used canonically.

Invocation:
palFk524( double r2000, double d2000, double dr2000, double dd2000, double p2000, double v2000, double $*$r1950, double $*$d1950, double $*$dr1950, double $*$dd1950, double $*$p1950, double $*$v1950 )
