|JEphem Ephemeris trail ELP 2000-82B|
ELP 2000-82B is a theory built at the BDL by M. Chapront-Touze and J. Chapront to compute lunar ephemeris.
The purpose of this page is to explain how it was integrated to JEphem.
The original files can be found at ftp://ftp.bdl.fr/pub/ephem/moon/elp82.
The constants of the subsequent lunar ephemeris are fitted to the numerical integration DE200/LE200 of the Jet Propulsion Laboratory and the arguments come from the semi-analytical theory ELP 2000-85.The time scale is Barycentric Dynamical Time (TDB).
