g. on account of precession), and You can find an infinity of such coordinate programs possible. Therefore the coordinate techniques most Employed in astronomy have to have their own personal date-reference as the coordinate systems of that sort are themselves in movement, e.g. by the precession of the equinoxes, nowadays generally settled into precessional factors, different precessions with the equator and of the ecliptic.
