SLA_CC2S

Cartesian to Spherical

ACTION:
Cartesian coordinates to spherical coordinates (single precision).
CALL:
CALL sla_CC2S (V, A, B)
GIVEN:

V

R(3)

[x,y,z] vector


RETURNED:

A,B

R

spherical coordinates in radians


NOTES:
(1)
The spherical coordinates are longitude (+ve anticlockwise looking from the +ve latitude pole) and latitude. The Cartesian coordinates are right handed, with the x-axis at zero longitude and latitude, and the z-axis at the +ve latitude pole.
(2)
If V is null, zero A and B are returned.
(3)
At either pole, zero A is returned.
