DESCRIPTION

17       n           The number of input Cartesian coordinates.
18
19       x           An  array containing the X component of the Cartesian coor‐
20                   dinates of the input data. (rlat[i],rlon[i]) is the lat/lon
21                   coordinate   corresponding   to  the  Cartesian  coordinate
22                   (x[i],y[i],z[i]) for i=0 to n-1.
23
24       y           An array containing the Y component of the Cartesian  coor‐
25                   dinates of the input data. (rlat[i],rlon[i]) is the lat/lon
26                   coordinate  corresponding  to  the   Cartesian   coordinate
27                   (x[i],y[i],z[i]) for i=0 to n-1.
28
29       z           An  array containing the Z component of the Cartesian coor‐
30                   dinates of the input data. (rlat[i],rlon[i]) is the lat/lon
31                   coordinate   corresponding   to  the  Cartesian  coordinate
32                   (x[i],y[i],z[i]) for i=0 to n-1.
33
34       rlat        An array containing the latitudes  of  the  output  coordi‐
35                   nates, in degrees.
36
37       rlon        An  array  containing  the longitudes of the output coordi‐
38                   nates, in degrees.
39

USAGE

41       c_csc2s is called to find the equivalent lat/lon coordinates to  speci‐
42       fied  Cartesian coordinates on a unit sphere.  The Cartesian coordinate
43       (1.,0.,0.) is converted to lat/lon coordinate  (0.,0.).  Latitudes  and
44       longitudes are assumed to be in degrees.
45

RETURN VALUE

47       c_csc2s does not return a value.
48

ACCESS

50       To use c_csc2s, load the NCAR Graphics library ngmath.
