cds-question@unistra.frsolar-systemsolar-system-planetsastrometryResults of the Galilean moons observationals taken with Normal Astrograph of the Pulkovo Observatory in 2016-2017 are presented. 761 positions of the Galilean moons of Jupiter in the system of the Gaia DR1 catalog (ICRF, J2000.0) and 854 differential coordinates of the satellites relative to each other were obtained. The mean errors in the satellites' normal places and the corresponding root-mean-square deviations are (eps)RA=0.0020", (eps)DE=0.0027", (sigm)RA=0.0546", and (sigm)DE=0.0757". The equatorial coordinates of the moons are compared to the motion theories of planets and satellites. On average, the (O-C) residuals in the both coordinates relative to the motion theories are less than 0.031". The best agreement with observations is achieved by a combination of the EPM2015 and V. Lainey-V.2.0|V1.1 motion theories, which yields the average (O-C) residuals of approximately 0.02". Peculiarities in the behavior of the (O-C) residuals and error values in Ganymede have been noticed.2018SoSyR..52..312Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/SoSyR/52.312CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/SoSyR/50.344 : Galilean moons + Jupiter positions (Narizhnaya, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/SoSyR/52.312https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/SoSyR/52.312http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/SoSyR/52.312https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/SoSyR/52.312https://vizier.iucaa.in/viz-bin/votable?-source=J/other/SoSyR/52.312http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/SoSyR/52.312GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/SoSyR/52.312/satsdat (Positions of Galilean satellites (1-Io, 2- Europa, 3-Ganymede, 4-Callisto))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/SoSyR/52.312/satsdat?https://vizier.iucaa.in/viz-bin/conesearch/J/other/SoSyR/52.312/satsdat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/SoSyR/52.312/satsdat?GETtext/xml+votable180.050000true174.10993753.936497220.0055555555555555566/26132 26134 26140 26142 26323 26326 26327 27007 27094 27099 27100 27102 27123 27128 27129https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/SoSyR/52.312?format=asciidefaultJ/other/SoSyR/52.312/satsatdDifferential mutual coordinates of Galilean satellitesrecnoRecord number assigned by the VizieR team.
