cds-question@unistra.fropen-star-clustersearly-type-starsx-ray-sourcesThe Orion Nebula Cluster (ONC) and the molecular cloud (OMC) in its vicinity have been observed with the ACIS-I detector on board the Chandra X-ray Observatory with 23hr exposure in two observations, on 1999 October 12 and 2000 April 1. We detect 1075 X-ray sources, most with sub-arcsecond positional accuracy. Ninety-one percent of the sources are spatially associated with known stellar members of the cluster, and an additional 7% are newly identified deeply embedded cloud members.2002ApJ...574..258Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/574/258CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/437/361 : Einstein survey of the Orion nebula region (Gagne+ 1994)J/ApJ/584/911 : X-rays in the Orion nebula cluster (Feigelson+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/574/258https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/574/258http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/574/258https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/574/258https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/574/258http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/574/258GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/574/258/table2 (ACIS ONC sources and stellar counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/574/258/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/574/258/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/574/258/table2?GETtext/xml+votable180.050000true83.65843-5.461220.0055555555555555566/21438 21439 22804 22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/574/258?format=asciiX-raydefaultJ/ApJ/574/258/table2ACIS ONC sources and stellar counterpartsrecnoRecord number assigned by the VizieR team.
