- ACTION:
- Spherical coordinates to Cartesian coordinates (single precision).
- CALL:
- CALL sla_CS2C (A, B, V)
- GIVEN:
-
A,B |
R |
spherical coordinates in radians: etc. |
- RETURNED:
-
V |
R(3) |
unit vector |
- NOTE:
- 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.
