Translation en Pascal pour Delphi par Patrick Chevalley le 10 novembre 1999.
SATXY.DLL inclu les coefficients des satellites de Mars,Jupiter,Saturne et Uranus de 1997 α 2020.
Exemple d'appel depuis Delphi :
**********************************************************************************
type double8 = array[1..8] of double;
Pdouble8 = ^double8;
Function Satxyfm(djc : double; ipla : integer; Pxx,Pyy : Pdouble8):integer; stdcall; external 'SATXY.DLL';
var i,j : integer;
xsat,ysat : double8;
jde : double;
begin
jde:=2451494.0
i:=satxyfm(jde,6,addr(xsat),addr(ysat));
end;

Low precision ephemerides of the main planetary satellites:
differential positions of the satellites of Mars,
Jupiter,Saturn, Uranus, given under the form of developments
in mixed functions.

CONTENTS: The files of this directory allow to compute the differential
coordinates of the main natural satellites with a precision of
0.5 arcsec for the period 1997-2020.
Beware: The files of this subdirectory have to be used
following the explanations given in the directory posxy,
see it for further explanations.
seqdir.f : This Fortran code source has to be compiled in order to allow
you to convert the ascii sequential files mars.xxxx, jupiter.xxxx,
saturne.xxxx, uranus.xxxx (where xxxx is the year)
into direct access files to be used by ephang.
diffpos.f : This Fortran program code source has to be compiled in order to
allow you to compute the differential coordinates of the
satellites by using the direct access files.
mars.xxxx | sequential files of coefficients for the year xxxx
jupiter.xxxx | (between 1997 and 2020)
saturne.xxxx |
uranus.xxxx |
