cds-question@unistra.frinfrared-photometryx-ray-sourcesyoung-stellar-objectsastronomical-object-identificationh-ii-regionsopen-star-clustersThe Massive Young star-forming complex Study in Infrared and X-rays (MYStIX) project requires samples of young stars that are likely members of 20 nearby Galactic massive star-forming regions. Membership is inferred from statistical classification of X-ray sources, from detection of a robust infrared excess that is best explained by circumstellar dust in a disk or infalling envelope and from published spectral types that are unlikely to be found among field stars. We present the MYStIX membership lists here, and describe in detail the statistical classification of X-ray sources via a "Naive Bayes Classifier."2013ApJS..209...32Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/209/32CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2013)B/mk : Catalogue of Stellar Spectral Classifications (Skiff, 2009-2013)II/293 : GLIMPSE Source Catalog (I + II + 3D) (IPAC 2008)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJS/209/31 : The MYStIX IR-Excess Source catalog (Povich+, 2013)J/ApJS/209/30 : MYStIX: Bayesian matching (Naylor+, 2013)J/ApJS/209/29 : MYStIX: MIR observations and catalogs (Kuhn+, 2013)J/ApJS/209/28 : MYStIX Wide-Field NIR data: crowded fields (King+, 2013)J/ApJS/209/27 : MYStIX: the Chandra X-ray sources (Kuhn+, 2013)J/ApJS/194/14 : A Pan-Carina YSO catalog (Povich+, 2011)J/ApJS/194/10 : NIR properties of YSO in the CCCP (Preibisch+, 2011)J/ApJS/194/5 : Carina OB stars in the CCCP catalog (Gagne+, 2011)J/ApJS/194/4 : Classification of CCCP X-ray sources (Broos+, 2011)J/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/ApJ/714/L285 : YSO candidates in M17 SWex (Povich+, 2010)J/ApJ/708/1760 : Flux estimations of faint X-ray sources (Getman+, 2010)J/ApJ/696/1278 : The extended star-forming environment of M17 (Povich+, 2009)J/MNRAS/384/675 : Monitoring low-mass stars in NGC 2362 (Irwin+ 2008)J/ApJS/169/353 : Chandra sources in M17 (Broos+, 2007)J/ApJS/168/100 : X-ray study of star-forming region NGC 6357 (Wang+, 2007)J/ApJ/671/605 : NGC 2264 and ONC PMS stars in the infrared (Cieza+, 2007)J/ApJ/642/972 : IR phot. of a star-forming core in NGC 2264 (Young+, 2006)J/MNRAS/371/252 : Southern B and Be stars (Levenhagen+, 2006)J/ApJS/160/353 : Membership of the Orion nebula population (Getman+, 2005)J/ApJS/160/319 : COUP: observations and source lists (Getman+, 2005)J/AJ/130/1145 : YSO near-infrared properties (Doppmann+, 2005)J/ApJ/562/446 : X-rays and protostars in Trifid nebula (Rho+, 2001)J/A+A/355/651 : HRI observations of PMS stars in NGC 2264 (Flaccomio+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/209/32https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/209/32http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/209/32https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/209/32https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/209/32http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/209/32GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/209/32/reg (List of the 20 nearby Galactic massive star-forming regions; table added by CDS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/209/32/reg?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/209/32/reg?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/209/32/reg?GETtext/xml+votable180.050000true161.079167-59.8891670.005555555555555556Cone search capability for table J/ApJS/209/32/mpcm (MPCM (MYStIX Probable Complex Members) sources and properties (table 2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/209/32/mpcm?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/209/32/mpcm?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/209/32/mpcm?GETtext/xml+votable180.050000true83.6227261-5.393730.005555555555555556Cone search capability for table J/ApJS/209/32/table7 (Counterparts to X-ray sources and classification probabilities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/209/32/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/209/32/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/209/32/table7?GETtext/xml+votable180.050000true85.3040089-1.91660890.0055555555555555565/10614 10615 6/1285 1287 1296 1298 3307 3649 14682 14704 21438 21439 22243 22249 22804 22805 22854 22855 23637 23639 28890 28891 28913 28915 29116 29118 29461 29463 29504 29506 30341 30352 37333 37872 37884 37886 37923 37926 38016 399072.0616683193919197e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/209/32?format=asciiX-rayInfrareddefaultJ/ApJS/209/32/regList of the 20 nearby Galactic massive star-forming regions; table added by CDSRegAbbreviated region namemeta.idcharprimaryrecnoRecord number assigned by the VizieR team.
