Description:
The files given here refer to the paper A&A 282, 663 (1994) which
concerns the following topics:
- numerical expressions for the precession quantities,
- mean elements for Moon and planets, from Mercury to Neptune,
- formulae for computing approximate ephemerides for Moon
and planets.
The files concern only precession and approximate ephemerides of
the planets.
The numerical expressions of precession are yielded by files :
prctable.doc, prcbdl94.f, prcupdt.f.
The formulae for computing approximate ephemerides of the planets
are available in file : planetap.f.
There is no file for the mean elements of Moon and planets because
these quantities are of a more specific use.
Approximate lunar ephemerides may be computed from tables in:
Chapront-Touze M., Chapront J. (1991)
"Lunar Tables and Programs from 4000 B.C. to A.D. 8000"
Willmann-Bell, Inc., Richmond, Virginia, USA.

expressions of precession BDL94 with new
values for general precession, obliquity
and ratios Sun mass / planet mass.

Note on *.f files:
Fortran77 code contains a subroutine with comments for usage
and a short program showing how the subroutine is called on Unix
workstations; for usage in a DOS 5.0 environment, just replace the
"C" in col.1 by a blank in a few lines for better screen management.
