cds-question@unistra.fropen-star-clusterspre-main-sequence-starsx-ray-sourcesinfrared-sourcesThe Chandra Orion Ultradeep project (COUP) observation described in a companion paper by Getman et al. (2005, Cat. J/ApJS/160/319) provides an exceptionally deep X-ray survey of the Orion Nebula Cluster and associated embedded young stellar objects. Membership of the region is important for studies of the stellar IMF, cluster dynamics, and star formation. The COUP study detected 1616 X-ray sources. In this study we confirm cloud membership for 1315 stars, identify 16 probable foreground field stars having optical counterparts with discrepant proper motions, and classify the remaining 285 X-ray sources, of which 51 are lightly and 234 heavily obscured.2005ApJS..160..353Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/160/353CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/160/319 : COUP: observations and source lists (Getman+, 2005)J/AJ/113/1733 : Orion Nebula Cluster population (Hillenbrand 1997)J/AJ/116/1816 : JHKLMNOPQ photometry in Orion cluster (Hillenbrand+, 1998)J/ApJ/540/236 : KH photometry of Orion Nebula Cluster (Hillenbrand+, 2000)J/A+A/396/513 : Stellar Rotation in the Orion Nebula Cluster (Herbst+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/160/353https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/160/353http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/160/353https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/160/353https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/160/353http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/160/353GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/160/353/table3 (COUP double sources with <3" separations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/160/353/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/160/353/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/160/353/table3?GETtext/xml+votable180.050000true83.7113869-5.4003650.005555555555555556Cone search capability for table J/ApJS/160/353/table4 (COUP stars with discrepant proper motions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/160/353/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/160/353/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/160/353/table4?GETtext/xml+votable180.050000true83.62304-5.398490.005555555555555556Cone search capability for table J/ApJS/160/353/table12 (Flaring or non-flaring COUP X-ray sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/160/353/table12?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/160/353/table12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/160/353/table12?GETtext/xml+votable180.050000true83.7755811-5.38505810.0055555555555555566/21438 21439 22804 22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/160/353?format=asciiX-rayInfrareddefaultJ/ApJS/160/353/table3COUP double sources with <3" separationsrecnoRecord number assigned by the VizieR team.
