- Description:
- The theory of the lunar motion consists of the series of the
- semi-analytical solution ELP2000-82. 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.

- Contents:
- The semi-analytical lunar theory ELP 2000-82 contains purely
- trigonometric series and Poisson series proportional to the time (t)
- or the square of the time (t2).
- 36 data files include the series related to various components of the
- theory for the 3 spherical coordinates: longitude, latitude and
- distance. Units are arcsecond for longitude and latitude, kilometer
- for distance. Arguments, constants and coordinate systems are
- described in the notice "Lunar solution ELP 2000-82B" (elp82b.ps).
- All this set allows to compute a high precision lunar ephemeris. A
- FORTRAN example is provided (EXAMPLE) which makes use of the basic
- subroutine ELP82B.

- Remarks :
- (1) The document elp82b.ps ("LUNAR SOLUTION ELP 2000-82B") can be
- requested directly to the authors. The sources which consist in 36
- files (the semi-analytical series) and the programs of use (example.f
- and elp82b.f) are also available on diskettes (DOS system).
- (2) The subroutine ELP82B and the program EXAMPLE (FORTRAN 77) are
- provided to simply illustrate the computation of an ephemeris. If the
- user wants to improve the rapidity of computation, it is recommended
- to transform files in direct access and/or to read series in memory
- once for all.
