I compare planet's BCRS positions computed using obj.at(t) by de430.bsp and data queried from Horizons web site. The difference is small enough.
But when I replace de430.bsp with de440.bsp, the di…

I am trying to track down what I think may be a bug in SOFA regarding polar motion. In their function Pvtob(), they do the standard rotation of the Earth by xp around the y axis and then yp around the…

There are two options for the coordinate system in Horizons:
- Earth mean equator and equinox of reference epoch ("frame"):
- Ecliptic and mean equinox of reference epoch ("ecliptic")
Currently we ar…
