10

DESCRIPTION

12       N           (integer, input) The number of coordinates to convert.
13
14       RLAT        (real,  input)  The  latitudes of the input coordinates, in
15                   degrees.
16
17       RLON        (real, input) The longitudes of the input  coordinates,  in
18                   degrees.
19
20       X,Y,Z       (real,  output)  The  Cartesian  coordinates  of the output
21                   points.
22

USAGE

24       CSS2C is called to find equivalent Cartesian coordinates  on  the  unit
25       sphere  to  latitude  and  longitude  coordinates.   The  coordinate 0.
26       degrees latitude and 0. degrees longitude is mapped  to  the  Cartesian
27       coordinate (1., 0.,0.).
