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.
