Notes
The algorithm for determining the sun/earth relative position is based on the simplified version of VSOP2000 that is part of ERFA. Compared to JPL’s ephemeris, it should be good to about 4 km (in the Sun-Earth vector) from 1900-2100 C.E., 8 km for the 1800-2200 span, and perhaps 250 km over the 1000-3000.
