[Stellarium-pubdevel] Ephemeris from the JPL?

Dear all,

By the way, I would like to ask you if someone has considered the
possibility of using the ephemeris files from the Jet Propulsion Laboratory
in Stellarium. These files are given for free and are extremely precise
(e.g., they consider the orbital precessions due to Relativity,
perturbations between the planets, and so on). Also, the algorithms to
compute planets positions from the provided tables are *extremely* fast.

I used these ephemeris for my works on Astrometry and I am very happy of
them. I think that a good choice for Stellarium would be the ephemeris
DE423 (which run from year 1799 to year 2200). Out of this ephemeris time
range, we could come back to the predictions by the plain Kepler's
equations.

Of course, I would be glad to help with the implementation of the new code
in the core, if you would be interested.

    Best Wishes!

              Ivan
