Hi Jerome and all, you have linked the same pdf twice. I think you meant the following two links: for the Chebyshev files: ftp://ftp.imcce.fr/pub/ephem/planets/vsop2013/ephemerides/README.pdf and for the elliptic elements: ftp://ftp.imcce.fr/pub/ephem/planets/vsop2013/solution/README.pdf As Jerom

OK, thanks for the links. I will try to find time, a bit later but hopefully still this year. (Want to have completely working DE431 first!) Kind regards, Georg On Sa, 3.10.2015, 01:46, JBerthier wrote: > Hi, > > VSOP2013 is the last release of the analytic planetary theory VSOP87. It > is easy

Hi, VSOP2013 is the last release of the analytic planetary theory VSOP87. It is easy to use. You can choose to use theseries of the elliptic elements (ftp://ftp.imcce.fr/pub/ephem/planets/vsop2013/ephemerides/README.pdf) or the Chebyshev files (ftp://ftp.imcce.fr/pub/ephem/planets/vsop2013/ep

Dear Theodor, thank you for the link, I will have a look in the next weeks. You are right, we are planning to have DE43x as option for advanced users, also with the possibility to use the file stored outside Stellarium folders (in case you are using it already in other software - no need to copy

Dear Georg, great to hear that the newest JPL data will be usable! (I assume it will be optional) If you want to cross-check your results using classical computation versus the new IAU computation path I'd be happy if my program would help: http://thaec.rascanu.de/ Installation instructions are i

Dear Theodor, thank you for your offer, but the DE43[01] challenge has been taken, there is a branch "socis2015-de430" on launchpad. Stellarium does not use SOFA and goes the "classical" path without ERA, so maybe your program would still interest me as it could be a way to check our results. So,
