EPM2004

The EPM2004 ephemerides were constructed over the 1880-2020 time interval
(JD 2407715.5-2458850.5) in the TDB time scale.
GM of all planets, the Sun, the Moon and value of Earth-Moon mass ratio
correspond to DE405.  EPM2004 is the basis for the Russian Astronomical
Yearbook since 2006.
Constants on EPM2004 ephemerides:
