Planetary Theories in rectangular and spherical variables: VSOP87 solution. Bretagnon P., Francou G. <Astron. Astrophys. 202, 309 (1988)> =1988A&A...202..309B Theorie du mouvement de l'ensemble des planetes (VSOP82). Bretagnon P. <Astron. Astrophys. 114, 278 (1982)> =1982A&A...114..278B
ADC_Keywords: Ephemerides ; Keywords: planets - ephemerides - celestial mechanics Description: The Planetary solutions VSOP87 (Variations Seculaires des Orbites Planetaires) are analytical solutions of the motion of the planets in different versions. The main version VSOP87 consists of the series in elliptic elements as in the case of VSOP82 solution and the other versions VSOP87 (A-B-C-D-E) are built in in rectangular and spherical variables. Authors' Address: P. Bretagnon, G. Francou Bureau des Longitudes, CNRS URA 707 77, Avenue Denfert-Rochereau 75014, Paris, France Tel : (33) 1 40 51 22 69 (33) 1 40 51 22 60 Fax : (33) 1 46 33 28 34 E-mail : Contents: The main version of VSOP87 is similar to the previous theory VSOP82. In the both cases the constants of integration have been determined by fitting to the numerical integration DE200 of the Jet Propulsion Laboratory. The various versions of VSOP87 are different from one to another in the type of coordinates and the reference frame. VSOP87 : heliocentric elliptic variables; equinox and ecliptic J2000. VSOP87A : heliocentric rectangular variables; equinox and ecliptic J2000. VSOP87B : heliocentric spherical variables; equinox and ecliptic J2000. VSOP87C : heliocentric rectangular variables; equinox and ecliptic of date. VSOP87D : heliocentric spherical variables; equinox and ecliptic of date. VSOP87E : barycentric rectangular variables; equinox and ecliptic J2000. A program EXAMPLE (Fortran 77) is provided which makes use of the subroutine VSOP87 which substitutes the time in the series of the solutions VSOP87. File Summary:

If the user wants to improve the rapidity of computation, it is recommended to transform files in direct access or to read series in memory once for all.
