cds-question@unistra.frmultiple-starsccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryWe present accurate CCD astrometric and photometric data for 31 nearby visual double stars in the standard filters BVRI. The observations were collected with a 1.3-m telescope in 2001-2002. The results consist of relative astrometric positions (epoch, angular separation and position angle) and differential BVRI photometry of the components. Mean errors are: 0.01" for the separation; 0.06{deg} for the position angle; and 0.015mag for the photometric data. Comparing the relative positions at different epochs, we evaluate the physical association of the systems. We additionally derive fractional masses and true separations for the most probable binary systems and, whenever orbits are available, also total and component masses.2004A&A...422.1023Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/422/1023CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/422/1023https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/422/1023http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/422/1023https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/422/1023https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/422/1023http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/422/1023GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/422/1023/table4 (Astrometric results and comparison of the relative positions with the Hipparcos data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/422/1023/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/422/1023/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/422/1023/table4?GETtext/xml+votable180.050000true1.42088745.8120810.0055555555555555566/447 824 1642 2747 3345 3507 3697 3751 5498 7665 10004 10089 10313 10388 10467 10771 11029 13323 13512 13883 14266 14456 15154 15311 19931 23137 26614 31720 31998 32380https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/422/1023?format=asciiOpticalInfrareddefaultJ/A+A/422/1023/table4Astrometric results and comparison of the relative positions with the Hipparcos dataHIPHIP (<I/239>) numbermeta.id;meta.mainintprimaryrecnoRecord number assigned by the VizieR team.
