 *  This routine is part of the General Astrodynamics Library  
 *  
 *  Description: 
 *  
 *  Julian Date to Besselian Epoch.  
 *  
 *  This routine is an independent translation of a FORTRAN routine  
 *  that is part of IAU's SOFA software collection.  
 *  
 *  Status:
 *  
 *     support routine.  
 *  
 *  Given:
 *  
 *     dj1,dj2             d        Julian Date (see note)  
 *  
 *  Returned:
 *  
 *     gal_epb             d        The result is the Besselian Epoch.  
 *  
 *  Note:  
 *  
 *  1) The Julian Date is supplied in two pieces, in the usual SOFA  
 *     manner, which is designed to preserve time resolution.  The  
 *     Julian Date is available as a single number by adding dj1 and  
 *     dj2. The maximum resolution is achieved if dj1 is 2451545D0  
 *     (J2000).
