       n           The number of input lat/lon coordinates.

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

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

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

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

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

       c_css2cd - convert from lat/lon coordinates to Cartesian coordinates.

       c_css2cd does not return a value.

           c_css2cd(n, rlat, rlon, x, y, z);

       c_css2cd  is  called  to find the equivalent Cartesian coordinates on a unit sphere to specified latitude
       and longitude coordinates.  The coordinate of 0. latitude and 0.  longitude  is  converted  to  Cartesian
       coordinate  (1.,0.,0.).  Latitudes  and  longitudes  are  assumed to be in degrees.  c_css2cd is a double
       precision version of c_css2c.
