 *  This routine is part of the General Astrodynamics Library  
 *  
 *  Description: 
 *  
 *     This routine transforms a pv-vector from the ICRF
 *     reference frame to the planet body fixed reference frame.
 *
 *  Status:
 *  
 *     support routine.  
 *  
 *  Given:
 *  
 *     icrf          d[2][3]        pv-vector in ICRF inertial frame
 *     alpha            d           Right ascension of planet spin axis ( radians )
 *     delta            d           Declination of planet spin axis ( radians )
 *     w                d           Prime meridian angle 
 *     omega            d           Planet rotation rate ( radians second^-1 )
 *  
 *  Returned:
 *  
 *     bfrf          d[2][3]        pv-vector in planet mean equator frame
 *
 *  Called:
 *
 *     gal_c2me      ICRF to mean equator transform
 *     gal_me2bf     mean equator to body fixed transform
