cds-question@unistra.frh-ii-regionspre-main-sequence-starsx-ray-sourcesThe Trifid Nebula, a young star-forming H II region, was observed for 16hr by the ACIS-I detector on board the Chandra X-Ray Observatory. We detected 304 X-ray sources, 30% of which are hard sources and 70% of which have near-infrared counterparts.2004ApJ...607..904Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/607/904CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 2002-)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/607/904https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/607/904http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/607/904https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/607/904https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/607/904http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/607/904GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/607/904/table1 (Catalog of X-ray sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/607/904/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/607/904/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/607/904/table1?GETtext/xml+votable180.050000true270.460875-22.9110.0055555555555555566/28913 28915https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/607/904?format=asciiX-raydefaultJ/ApJ/607/904/table1Catalog of X-ray sourcesrecnoRecord number assigned by the VizieR team.
