       CALL CSC2S (N, X, Y, Z, RLAT, RLON)

       CSC2S  is called to find equivalent latitude and longitude coordinates to specified Cartesian coordinates
       on the unit sphere.  The coordinate (1.,0.,0.) is mapped to the  latitude/longitude  coordinate  (0.,0.).
       The latitude/longitude coordinates are returned in degrees.
