Coordinate Functions

• Convert -> Angle <-> Decimal Degrees
• Convert -> Right Ascension <-> Hour Angle
• Convert -> Equatorial Coordinates <-> Horizon Coordinates
• Calculate -> Obliquity of the Ecliptic
• Convert -> Ecliptic Coordinates <-> Equatorial Coordinates
• Convert -> Equatorial Coordinates <-> Galactic Coordinates
• Calculate -> Angle between two objects
• Calculate -> Rising and Setting times for an object
• Calculate -> Precession (corrected coordinates between two epochs)
• Calculate -> Nutation (in ecliptic longitude and obliquity) for a Greenwich date
• Calculate -> Effects of aberration for ecliptic coordinates
• Calculate -> RA and Declination values, corrected for atmospheric refraction
• Calculate -> RA and Declination values, corrected for geocentric parallax
• Calculate -> Heliographic coordinates
• Calculate -> Carrington rotation number
• Calculate -> Selenographic (lunar) coordinates (sub-Earth and sub-Solar)
