cds-question@unistra.fropen-star-clustersdwarf-starsinfrared-photometryvisible-astronomyphotometryh-alpha-photometryWe have performed deep wide-field CCD photometry of the young open cluster NGC 2264 to study the extent of star-forming regions (SFRs) and the shape of the initial mass function. In this paper, we present VRI and H{alpha} photometry for more than 67,000 stars. From the spatial distribution of the selected H{alpha} emission stars, we identify two active SFRs and a less active halo region surrounding these two SFRs. There are several H{alpha} emission stars in the field region outside the halo region, and these may be newly formed stars in the Mon OB1 association surrounding the cluster. The locus of pre-main-sequence (PMS) stars in the I_C_ versus V-I_C_ diagram is revised from the distribution of H{alpha} and X-ray emission stars in the diagram.2008AJ....135..441Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/441CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/127/2659 : CHANDRA observations of NGC 2264 (Ramirez+, 2004)J/A+A/345/521 : BVRI photometry of NGC 2264 (Flaccomio+, 1999)J/AJ/114/2644 : UBVRIHa photometry of NGC2264 (Sung+, 1997)J/AJ/128/1684 : NGC 2264: VRIH{alpha} photometry (Sung+, 2004)J/AJ/129/829 : H{alpha} emission stars in NGC 2264 (Dahm+, 2005)J/AJ/127/1117 : Halpha emission-line stars in NGC2264 (Reipurth+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/441https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/441http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/441https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/441https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/441http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/441GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/441/table3 (Photometric data from CHFT observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/441/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/441/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/441/table3?GETtext/xml+votable180.050000true99.88691679.94383330.005555555555555556Cone search capability for table J/AJ/135/441/table8 (Photometric data from SSO WFI observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/441/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/441/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/441/table8?GETtext/xml+votable180.050000true99.808958310.39913890.005555555555555556Cone search capability for table J/AJ/135/441/table12 (Stars below the Main Sequence ("BMS" stars))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/441/table12?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/441/table12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/441/table12?GETtext/xml+votable180.050000true99.97954179.36472220.005555555555555556Cone search capability for table J/AJ/135/441/table9 (Re-analysis of data from SSO 1-m telescope and SITe 2K CCD)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/441/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/441/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/441/table9?GETtext/xml+votable180.050000true99.93659.50727780.0055555555555555565/5909 6/22270 22271 23808 238108.650015785639275e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/441?format=asciiInfraredOpticaldefaultJ/AJ/135/441/table3Photometric data from CHFT observationsrecnoRecord number assigned by the VizieR team.
