Web• For instance “2000.0” would specify coordinates in a system when the Earth’s precession made the (distant) night sky look as it was at midnight on Jan 1, 2000 • Because the equatorial coordinate system is set by the position of the Sun on the Vernal Equinox, this specification (e.g., 2000.0) is called an equinox http://astro.phy.vanderbilt.edu/~runnojc1/teaching/ASTR8020/handouts/802005.pdf

Description of Heliospheric Coordinate Systems - NASA

The heliocentric ecliptic system describes the planets' orbital movement around the Sun, and centers on the barycenter of the Solar System (i.e. very close to the center of the Sun).
