cds-question@unistra.frsolar-system-planetsastrometry229 CCD positions of Nereid taken between 1993 and 1998 are presented. Many of the observations were taken near the periapsis. Considering also the other published positions we have a good distribution of the observations on the eccentric orbit of the satellite. Using a numeric integration method we fitted all these observations in order to determine one state vector for the orbit. The observed minus calculated standard deviation for all observations is 0.23", and for our observations it is 0.16".1999A&AS..136..445Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/136/445CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/120/107 : 1989-1994 CCD observations of Triton (Veiga+ 1996)J/A+AS/121/65 : 1990-1994 Saturn's satellites astrometry (Harper+ 1997)J/A+AS/131/291 : 1995-1997 CCD positions of Triton (Veiga+ 1998)J/A+AS/136/257 : Saturn's satellites in 1995/97 (Harper+ 1999)J/A+AS/139/305 : Position of Saturn's satellites (1982-1988) (Veiga+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/136/445https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/136/445http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/136/445https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/136/445https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/136/445http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/136/445GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/136/445/table1 (List of observed positions of the Neptunian satellite)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/136/445/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/136/445/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/136/445/table1?GETtext/xml+votable180.050000true291.8508125-21.227750.0055555555555555566/48124 48126 48746 48781-48783 48790 48792 48801https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/136/445?format=asciidefaultJ/A+AS/136/445/table1List of observed positions of the Neptunian satelliterecnoRecord number assigned by the VizieR team.
