Any observation made from Earth at a specific time gives two spherical coordinates. We may chose whether these relate to the celestial equator (right as

It provides accurate conversions between ecliptic and equatorial coordinates, and between geocentric and heliocentric coordinates, for various epochs. The individual transformations
