NAME

       c_csc2sd - convert from Cartesian coordinates to lat/lon coordinates.

FUNCTION PROTOTYPE

           void   c_csc2sd(int, double *, double *, double *, double *, double *);

SYNOPSIS

           c_csc2sd(n, x, y, z, rlat, rlon);

DESCRIPTION

       n           The number of input Cartesian coordinates.

       x           An  array containing the X component of the Cartesian coordinates of the input
                   data.  (rlat[i],rlon[i])  is  the  lat/lon  coordinate  corresponding  to  the
                   Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1.

       y           An  array containing the Y component of the Cartesian coordinates of the input
                   data.  (rlat[i],rlon[i])  is  the  lat/lon  coordinate  corresponding  to  the
                   Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1.

       z           An  array containing the Z component of the Cartesian coordinates of the input
                   data.  (rlat[i],rlon[i])  is  the  lat/lon  coordinate  corresponding  to  the
                   Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1.

       rlat        An array containing the latitudes of the output coordinates, in degrees.

       rlon        An array containing the longitudes of the output coordinates, in degrees.

USAGE

       c_csc2sd  is  called  to  find  the  equivalent lat/lon coordinates to specified Cartesian
       coordinates on a unit sphere.  The Cartesian coordinate (1.,0.,0.) is converted to lat/lon
       coordinate  (0.,0.). Latitudes and longitudes are assumed to be in degrees.  c_csc2sd is a
       double precision version of c_csc2s.

RETURN VALUE

       c_csc2sd does not return a value.

ACCESS

       To use c_csc2sd, load the NCAR Graphics library ngmath.
