Re: [Stellarium-pubdevel] Ephemeris from the JPL?

[JBerthier <ber...@im...>]

Hi,

If you are interested I can provide the files of coefficients of the new 
VSOP analytical planetary theory (Stellarium uses VSOP87 until now, 
right?). But I'm not qualified to write any code for stellarium. The 
advantage of an analytical theory is that there's almost no limit in time.

cheers,
jerome
