cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryccd-photometryWe present the results of a deep, wide-field CCD survey for the open cluster NGC 3532. Our new BV(RI)c photometry effectively covers a one square degree area and reaches an unprecedented depth of V~21 to reveal that NGC 3532 is a rich open cluster that harbors a large number of faint, low-mass stars. We employ a number of methods to reduce the impact of field star contamination in the cluster color-magnitude diagrams (CMDs), including supplementing our photometry with JHKs data from the 2MASS catalog. These efforts allow us to define a robust sample of candidate main-sequence stars suitable for a purely empirical determination of the cluster's parameters by comparing them to the well-established Hyades main sequence.2011AJ....141..115Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/115CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/115https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/115http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/115https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/115https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/115http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/115GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/141/115/table2 (BV(RI)_c_ CCD photometry and equatorial coordinates for stars in NGC 3532)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/115/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/115/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/115/table2?GETtext/xml+votable180.050000true167.4290417-58.20947220.005555555555555556Cone search capability for table J/AJ/141/115/known (New (table3) and previous (table4) photometry for previously studied stars in NGC 3532)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/141/115/known?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/141/115/known?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/141/115/known?GETtext/xml+votable180.050000true165.6045833-58.76038890.0055555555555555566/37927 37932 37933 37938 379442.367228618189496e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/141/115?format=asciiOpticalInfrareddefaultJ/AJ/141/115/table2BV(RI)_c_ CCD photometry and equatorial coordinates for stars in NGC 3532Seq[1/316367] Sequential identification numbermeta.id;meta.mainintprimarychiMean value of {chi}stat.fit.chi2floatXpixX-coordinate in finding chart (1)pixpos.cartesian.x;instr.detfloatYpixY-coordinate in finding chart (1)pixpos.cartesian.y;instr.detfloatrecnoRecord number assigned by the VizieR team.
