cds-question@unistra.frephemeridessolar-system-planetsWe present a new model of the four Galilean satellites Io, Europa, Ganymede and Callisto, able to deliver accurate ephemerides over a very long time span (several centuries). In the first paper (Lainey et al., 2004A&A...420.1171L) we gave the equations of the dynamical model. Here we present the fit of this model to the observations, covering more than one century starting from 1891. Our ephemerides, based on this first fit called L1, are available on the web page of the IMCCE at the URL http://www.imcce.fr/ephemeride_eng.html .2004A&A...427..371Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/427/371CatalogResearchIsServedByTAP VizieR generic servicerelated-tohttp://www.imcce.fr/ephemeride_eng.html : Ephemerides server Home PageJ/A+A/314/312 : Galilean satellites mutual events in 1997 (Arlot 1996)J/A+A/383/719 : Galilean Satellites mutual events 2002-2003 (Arlot, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/427/371https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/427/371http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/427/371https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/427/371https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/427/371http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/427/371GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/427/371/table4Mean and standard deviation on right ascension and declination for each satelliterecnoRecord number assigned by the VizieR team.
