NAME

c_csc2s - convert from Cartesian coordinates to lat/lon coordinates.

FUNCTION PROTOTYPE

    void   c_csc2s(int, float *, float *, float *, float *, float *);

SYNOPSIS

    c_csc2s(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_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.

RETURN VALUE

c_csc2s does not return a value.

ACCESS

To use c_csc2s, load the NCAR Graphics library ngmath.
