cds-question@unistra.fropen-star-clustersccd-photometryvisible-astronomymedium-band-photometryCCD photometry on the intermediate-band vbyCaH{beta} system is presented for the metal-deficient open cluster NGC 2420. Restricting the data to probable single members of the cluster using the CMD and the photometric indices alone generates a sample of 106 stars at the cluster turnoff.2006AJ....131..461Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/461CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/119/2282 : Stromgren photometry of IC 4651 (Anthony-Twarog+, 2000)J/AJ/125/1383 : Stromgren photometry of NGC 6253 (Anthony-Twarog+, 2003)J/AJ/127/1000 : Stromgren photometry of NGC 3680 (Anthony-twarog+, 2004)J/AJ/129/872 : Stromgren photometry of NGC 2243 (Anthony-Twarog+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/461https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/461http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/461https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/461https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/461http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/461GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/461/table1 (Extended Stromgren photometry in NGC 2420)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/461/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/461/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/461/table1?GETtext/xml+votable180.050000true114.5716011121.463320830.0055555555555555566/4783 6148 6149https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/461?format=asciiOpticaldefaultJ/AJ/131/461/table1Extended Stromgren photometry in NGC 2420recnoRecord number assigned by the VizieR team.
