cds-question@unistra.frsolar-system-planetsastrometryIn this paper, we publish measurements of 864 positions of the major satellites of Uranus made in 1995-1997 using CCD (1024"*1024") detectors attached to the 1.56-metre Astrometric Telescope at the Sheshan station near Shanghai. Analysis of the data as inter-satellite positions shows that the observations of Ariel, Umbriel, Titania and Mirand relative to Oberon have root-mean-square residuals of 0.03"-0.05", except for the innermost and faintest satellite Miranda, whose residuals exceeded 0.08" due to the proximity of Uranus.2002A&A...391..775Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/391/775CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/130/77 : Astrometry of Satellites of Uranus (Jones+ 1998)J/A+AS/121/65 : 1990-1994 Saturn's satellites astrometry (Harper+ 1997)J/A+AS/139/305 : Position of Saturn's satellites (1982-1988) (Veiga+, 1999)J/A+AS/139/47 : 1995 Saturnian satellites mutual events (Emelianov+, 1999)J/A+A/383/296 : Saturnian Satellites positions (1996-2000) (Peng+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/391/775https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/391/775http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/391/775https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/391/775https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/391/775http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/391/775GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/391/775/tablea1Observations made on 1995-1997recnoRecord number assigned by the VizieR team.
