   Relativistic Corrections 
   ========================= 
 
   This routine does not attempt to perform either general or 
   special relativistic corrections in computing the various 
   aberration corrections.  For many applications relativistic 
   corrections are not worth the expense of added computation 
   cycles.  If however, your application requires these additional 
   corrections we suggest you consult the astronomical almanac (page 
   B36) for a discussion of how to carry out these cor
