cds.astro.Equatorial
public abstract class Equatorial
This abstract class introduces the specificities of the equatorial
coordinates.
An equatorial coordinate system is a system linked to the Earth,
and therefore varies with the long-term Earth motion (precession).
A full definition of this frame therefore requires the knowledge
of an Equinox which specifies when exactly this frame coincides with
the Earth frame.
