Abstract


   CSPICE_RECRAD converts rectangular (Cartesian) coordinates to
   right ascension, declination coordinates. All coordinates 
   are expressed as double precision values.

   For important details concerning this module's function, please refer to
   the CSPICE routine recrad_c.

I/O


   Given:

      rectan   a double precision 3-vector or 3xN array
               containing the rectangular coordinates of a 
               position or set of positions

   the call:
   
      cspice_recrad, rectan, radius, ra, dec
   
   returns:
   
      radius   a double precision scalar or N-vector describing 
               the distance of the position from origin.

      ra       a double precision scalar or N-vector describing
               the right ascension of the position as measured in 
               radians.

      dec      a double precision scalar or N-vector describing
               the declination of the position as measured in radians.

               'radius', 'ra', and 'dec' return with the same 
               order (N) as 'rectan'.
