========================== ============================ IMCCE - Observatoire de Paris Containt of the directory: /pub/ephem/satel/NOE/SATURNE/ 2011, April 27 =========================== ============================ CONTENTS: This file provides the ephemerides of the eight main Saturnian satellites, Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion and Iapetus. AUTHOR : V. Lainey ADDRESS : IMCCE - Observatoire de Paris 77 av. Denfert Rochereau, F-75014 PARIS Phone: (1) 40 51 22 72 Fax: (1) 46 33 28 34 e-mail: lainey@imcce.fr README FILE: ------------ These ephemerides are based on a numerical model (NOE) fitted to the observations dispatched from 1886 to 2009. These ephemerides are available only for the period [1875:2022]. For an extended use, feel free to contact us by email at the following address: lainey@imcce.fr The expected accuracy of these ephemerides is highly sensitive on the satellite and epoch of concern. Over the whole covered period, we estimate it to be about 600 km for the six innermost moons, and 1,800 km for Hyperion and Iapetus. These ephemerides are available in SPICE format (Chebychev polynomia in simple ASCII files are available on request). More informations concerning the use of SPICE files (.bsp file) are available here: http://naif.jpl.nasa.gov/naif/documentation.html Units: ------ Positions and velocities are delivered in kilometres and kilometres per second.
