A total of 395 X-ray point sources are detected, 299 of which (76%) have an optical or near-infrared (NIR) counterpart identified from deep FLAMINGOS images. From X-ray and mass sensitivity limits, we infer a total population of ~1700 young stars in the survey region. Based on smoothed stellar surface density maps, we investigate the spatial distribution of the X-ray sources and define three distinctive structures and substructures within them. Structures B and C are associated with previously known embedded IR clusters, while structure A is a new X-ray-identified unobscured cluster. A high-mass protostar RMCX 89=IRAS 06306+0437 and its associated sparse cluster are studied.2009ApJ...696...47Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/696/47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/ApJ/675/464 : Chandra observations of NGC 2244 (Wang+, 2008)J/ApJ/660/1532 : Spitzer/IRAC-MIPS survey of NGC 2244 (Balog+, 2007)J/A+A/384/890 : BVRIHalpha photometry of NGC 2244 X-ray stars (Berghoefer+,J/ApJ/574/258 : X-ray-emitting young stars in the Orion nebula (Feigelson+,J/ApJ/428/693 : Rosette Nebula and Maddalena Cloud structures (Williams+ 1994)http://flamingos.astro.ufl.edu/extragalactic/data.html : FLAMINGOS datahttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/696/47https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/696/47http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/696/47https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/696/47https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/696/47http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/696/47GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/696/47/table5 (X-ray stellar clusters and infrared counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/696/47/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/696/47/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/696/47/table5?GETtext/xml+votable180.050000true98.158334.771670.005555555555555556Cone search capability for table J/ApJ/696/47/catalog (Chandra catalog of primary and tentative X-ray sources, with stellar counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/696/47/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/696/47/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/696/47/catalog?GETtext/xml+votable180.050000true98.13515814.61825110.0055555555555555566/22243 222498.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/696/47?format=asciiX-rayOpticalInfrareddefaultJ/ApJ/696/47/table3X-ray spectroscopy for brighter RMCX sourcesNotesAdditional notes (5)meta.notecharrecnoRecord number assigned by the VizieR team.
