Function skyDistanceRadians( ra1, dec1, ra2, dec2 )
- Description:
-
Calculates the separation (distance around a great circle) of
two points on the sky in radians.
- Parameters:
-
- ra1 (floating point)
- right ascension of point 1 in radians
- dec1 (floating point)
- declination of point 1 in radians
- ra2 (floating point)
- right ascension of point 2 in radians
- dec2 (floating point)
- declination of point 2 in radians
- Return Value (floating point):
- angular distance between point 1 and point 2 in radians
- Signature:
- double skyDistanceRadians(double, double, double, double)
