cds-question@unistra.frmultiple-starsccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryRecent CCD observations were performed in the period 1998-2004 for a large sample of visual double and multiple stars selected from the Hipparcos Catalogue (Cat. <I/239>) and/or from the Gliese Catalogue of Nearby Stars (Cat. <V/70>). Accurate astrometric and photometric data allowing us to characterise the individual components are provided. These data are compared to Hipparcos data or to data from an older epoch to assess the nature of the observed systems. We simultaneously apply a Moffat-Lorentz profile with a similar shape to all detected components and adjust the profile parameters from which we obtain the relative astrometric position (epoch, position angle, angular separation) as well as differential multi-colour photometry (filters (B)VRI).2007A&A...464..641Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/464/641CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/274 : CCDM (Catalog of Components of Double Multiple stars (Dommanget+ 2002)J/A+A/374/132 : CCD photometry and astrometry of double stars (Lampens+, 2001)J/A+A/422/1023 : Nearby visual double stars UBVRI photometry (Strigachev+ 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/464/641https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/464/641http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/464/641https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/464/641https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/464/641http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/464/641GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/464/641/table4 (Astrometry of the observed stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/464/641/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/464/641/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/464/641/table4?GETtext/xml+votable180.050000true1.420886945.81208080.0055555555555555566/172 447 474 648 721 811 1045 1429 1547 1642 1911 2331 2363 2413 2505 2714 2747 2883 2966 3345 3743 3837 4240 4336 4708 5533 6281 6410 8790 9442 10313 12378 13179 13192 13266 13308 13323 13350 13395 13517 13567 13651 13723 13946 14009 14044 14053 14353 14386 14410 14576 14772 15683 15724 15959 17890 18087 20027 20037 21925 22010 22120 22148 22636 22927 22960 23660 23867 24252 24347 29855 30638 31751https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/464/641?format=asciiOpticalInfrareddefaultJ/A+A/464/641/table4Astrometry of the observed starsrecnoRecord number assigned by the VizieR team.
