.SH DESCRIPTION
.IP n 12
The number of input Cartesian coordinates.
.IP x 12
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. 
.IP y 12
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. 
.IP z 12
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. 
.IP rlat 12
An array containing the latitudes of the output coordinates,
in degrees. 
.IP rlon 12
An array containing the longitudes of the output coordinates,
in degrees. 
.SH USAGE
c_csc2s 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. 
.SH RETURN VALUE
c_csc2s does not return a value.
.SH ACCESS
To use c_csc2s, load the NCAR Graphics library ngmath.
