cds-question@unistra.frpre-main-sequence-starsx-ray-sourcesinfrared-photometryWe present results of Chandra observations of two flanking fields (FFs) in Orion, outside the Orion Nebula Cluster (ONC). We present a catalog of 417 sources, which includes X-ray luminosity, optical and infrared photometry, and X-ray variability information.2004AJ....128..787Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/128/787CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/127/2659 : CHANDRA observations of NGC 2264 (Ramirez+, 2004)J/AJ/119/3026 : Circumstellar disk candidates in Orion (Rebull+, 2000)J/AJ/121/1676 : ONC low-mass stars photometry (Rebull+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/128/787https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/128/787http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/128/787https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/128/787https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/128/787http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/128/787GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/128/787/table1 (The Catalog of X-Ray Sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/787/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/787/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/787/table1?GETtext/xml+votable180.050000true83.6779167-4.70424830.005555555555555556Cone search capability for table J/AJ/128/787/optir (Optical and near-infrared sources with X-Ray Counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/787/optir?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/787/optir?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/787/optir?GETtext/xml+votable180.050000true83.67756667-4.704127780.0055555555555555566/21438 21439 22805https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/128/787?format=asciiX-rayInfrareddefaultJ/AJ/128/787/table1The Catalog of X-Ray SourcesrecnoRecord number assigned by the VizieR team.
