Abstract
New version of lunar part of EPM ephemeris (EPM-ERA 2010) is presented. This version differs from previous EPM-ERA2008 ephemeris by the following points: — tidal perturbations in the rotational Lunar motion are computed with retarded argument; — 17131 LLR observations instead of 16320 were used in the process — the new version was transformed in the new ERA-Windows (previous version was in DOS). Investigation shows that the inner accuracy of DE ephemeredes (5.4-5.7 cm) is slightly better than that of EPM-ERA2010 (6.8 cm). But the accuracy of DE ephemerides cannot be used by an independent researcher because it is not possible to feed back the estimated corrections to their parameters (except coordinates of the stations and reflectors).

AB - New version of lunar part of EPM ephemeris (EPM-ERA 2010) is
presented. This version differs from previous EPM-ERA2008 ephemeris
by the following points: — tidal perturbations in the rotational
Lunar motion are computed with retarded argument; — 17131 LLR
observations instead of 16320 were used in the process — the new
version was transformed in the new ERA-Windows (previous version was
in DOS). Investigation shows that the inner accuracy of DE
ephemeredes (5.4-5.7 cm) is slightly better than that of EPM-ERA2010
(6.8 cm). But the accuracy of DE ephemerides cannot be used by an
independent researcher because it is not possible to feed back the
estimated corrections to their parameters (except coordinates of the
stations and reflectors).
