cds-question@unistra.frsolar-system-planetsastrometryAccurate positional measurements of planets and satellites are used to improve our knowledge of their dynamics and to infer the accuracy of planet and satellite ephemerides. In the framework of the FP7 ESPaCE project, we provide positions of Mars, Phobos and Deimos taken with the U.S. Naval Observatory 26-inch refractor during the 1971 opposition of the planet. These plates were measured with the digitizer of the Royal Observatory of Belgium and reduced through an optimal process that includes image, instrumental and spherical corrections to provide the most accurate data.2014A&A...572A.104Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/572/A104CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/545/A144 : Astrometric observations of Deimos (Pasewaldt+, 2012)J/A+A/487/755 : CCD observations of Martian Satellites (Veiga+, 2008)J/A+A/488/361 : Mars Express astrometric obs. of Phobos (Willner+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/572/A104https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/572/A104http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/572/A104https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/572/A104https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/572/A104http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/572/A104GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/572/A104/mars71 (USNO astrometric data of Mars (1971))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/572/A104/mars71?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/572/A104/mars71?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/572/A104/mars71?GETtext/xml+votable180.050000true322.89890611-21.835686940.005555555555555556Cone search capability for table J/A+A/572/A104/phobos71 (USNO astrometric data of Phobos (1971))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/572/A104/phobos71?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/572/A104/phobos71?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/572/A104/phobos71?GETtext/xml+votable180.050000true322.90890194-21.834846110.005555555555555556Cone search capability for table J/A+A/572/A104/deimos71 (USNO astrometric data of Deimos (1971))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/572/A104/deimos71?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/572/A104/deimos71?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/572/A104/deimos71?GETtext/xml+votable180.050000true322.92358306-21.832598890.0055555555555555566/48349 48351 48372 48517-48518https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/572/A104?format=asciidefaultJ/A+A/572/A104/mars71USNO astrometric data of Mars (1971)recnoRecord number assigned by the VizieR team.
