Sky Coordinate Conversion Program

skycoor is a utility for converting coordinates between various systems, representations, and equinoxes.

J2000 and B1950 coordinates, at any equinox, may be represented as fractional degrees or colon-separated hours:minutes:seconds degrees:minutes:seconds.

Galactic and ecliptic coordinates are always represented as fractional degrees.

Ecliptic coordinates should include a year, using the -y command.

Coordinates must always include the coordinate system, except when using the -r option to find the distance between two sky positions, when they must not be included.
