SLA_CS2C
Spherical to Cartesian
-
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.
