Function raFK4toFK5Radians( raFK4, decFK4, bepoch )
- Description:
-
Converts a B1950.0 FK4 position to J2000.0 FK5 yielding Right Ascension.
This assumes zero proper motion in the FK5 frame.
The
bepoch
parameter is the epoch at which the position in
the FK4 frame was determined.
- Parameters:
-
- raFK4 (floating point)
- right ascension in B1950.0 FK4 system (radians)
- decFK4 (floating point)
- declination in B1950.0 FK4 system (radians)
- bepoch (floating point)
- Besselian epoch
- Return Value (floating point):
- right ascension in J2000.0 FK5 system (radians)
- Signature:
- double raFK4toFK5Radians(double, double, double)
