Functions

relativePosition(double ra1, double dec1, double ra2, double dec2) → double

Position angle from point 1 to point 2.

sep(double ra1, double dec1, double ra2, double dec2) → double

Angular separation between two equatorial positions.

sepHav(double ra1, double dec1, double ra2, double dec2) → double

Angular separation using haversine formula (better for small angles).
