cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryccd-photometryWe present broadband BVI photometry for the open cluster NGC 6791, based upon analysis of 1764 individual CCD images. Data tables listing measured magnitudes and standard errors, image-quality indices, a variability index, and equinox J2000.0 equatorial coordinates for 14,342 stars to V~24 have been made available to the public through the services of the Canadian Astronomy Data Centre. Equatorial coordinates only have been provided for a further 1916 stars, the photometry for which we were unable to calibrate because of lack of color information.2003PASP..115..413Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/115/413CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASP/110/533 : BR photometry of Fornax bright stars (Stetson+ 1998)J/AJ/108/585 : UBVI photometry of NGC 6791 (Montgomery+, 1994)J/A+AS/114/1 : CCD UBVI photometry of NGC 6791 (Kaluzny+, 1995)J/AJ/123/3460 : Low-amplitude variables in NGC 6791 (Mochejska+, 2002)J/AJ/129/656 : Infrared photometry of NGC 6791 (Carney+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/115/413https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/115/413http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/115/413https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/115/413https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/115/413http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/115/413GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/115/413/catalog (Main data table)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/115/413/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/115/413/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/115/413/catalog?GETtext/xml+votable180.050000true290.028416737.77188890.0055555555555555566/14573 14575https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/115/413?format=asciiOpticalInfrareddefaultJ/PASP/115/413/catalogMain data tableSBGSequential identification number (1)meta.id;meta.mainintprimaryxFlag set to x if crossids available in Table crossidmeta.ref.urlcharXposX in accompanying image (2)pixpos.cartesian.x;obs.imagefloatYposY in accompanying image (2)pixpos.cartesian.y;obs.imagefloatBmag?
