cds-question@unistra.frx-ray-sourcessurveysnebulaestellar-associationsThe Chandra Carina Complex Project (CCCP) provides a sensitive X-ray survey of a nearby starburst region over >1deg^2^ in extent. Thousands of faint X-ray sources are found, many concentrated into rich young stellar clusters. However, significant contamination from unrelated Galactic and extragalactic sources is present in the X-ray catalog. We describe the use of a Naive Bayes classifier to assign membership probabilities to individual sources, based on source location, X-ray properties, and visual/infrared properties. For the particular membership decision rule adopted, 75% of CCCP sources are classified as members, 11% are classified as contaminants, and 14% remain unclassified. The resulting sample of stars likely to be Carina members is used in several other studies, which appear in this special issue devoted to the CCCP.2011ApJS..194....4Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)http://en.wikipedia.org/wiki/Naive_Bayes_classifier : Naive Bayes classifierhttp://cxc.harvard.edu/ciao/caveats/psf_artifact.html : about Chandra PSFhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/194/4https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/194/4http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/194/4https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/194/4https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/194/4http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/194/4GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/194/4/table5 (Classification quantities for CCCP sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/4/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/4/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/4/table5?GETtext/xml+votable180.050000true159.79145806-59.787378890.0055555555555555566/37333 37335 37930 37931 38016 38017 38018https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/194/4?format=asciiX-raydefaultJ/ApJS/194/4/table5Classification quantities for CCCP sourcesrecnoRecord number assigned by the VizieR team.
