In theJ.P.L. the first ephemeris used for Lunar ranging was LE 16 (Garthwaite, Holdridge & Mulholland 1970)5 that included the positions of planets taken in another general integration program (DE 19, Devine 1967), while the source ephemeris for the Moon was based on Brown-Eckert improved theory.

We use the Lie Transform as perturbation method; the solution is developed in powers of the small factors linked to J 2 and C 22.
