Data used to built INPOP ephemerides are available on the APDB data base.


The orbital solutions of the Sun, the eight planets, the dwarf planet Pluto and the Moon, the libration of the Moon and the time scale transformation TT-TDB are available as binary or text data files.
The binary and text data files provide the rectangular coordinates (x,y,z) in kilometers of the bodies with respect to the International Celestial Reference Frame (ICRF). The librations are given in radians. The time scale transformation TT-TDB is given in seconds for the files including it.
