cds-question@unistra.frstellar-associationsinfrared-photometryvisible-astronomyWide-band photometryJohnson CCD photometry was performed in the two subgroups of the association Cepheus OB3, for selected fields each containing at least one star with previous UBV photoelectric photometry. Photometry for about 1000 stars down to visual magnitude 21 is provided, although the completeness tests show that the sample is complete down to V=19mag. Individual errors were assigned to the magnitude and colours for each star. Colour-colour and colour-magnitude diagrams are shown. Astrometric positions of the stars are also given. Description of the reduction procedure is fully detailed.1995A&AS..114..489Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/114/489CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/114/489https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/114/489http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/114/489https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/114/489https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/114/489http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/114/489GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/114/489/table5 (UBVRI photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/114/489/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/114/489/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/114/489/table5?GETtext/xml+votable180.050000true343.03666762.3258330.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/114/489?format=asciiOpticalInfrareddefaultJ/A+AS/114/489/table5UBVRI photometryrecnoRecord number assigned by the VizieR team.
