cds-question@unistra.fropen-star-clustersx-ray-sourcesinfrared-photometryvisible-astronomybroad-band-photometryThis is the first paper of a series devoted to the {lambda} Orionis star-forming region, Orion's Head, from the X-ray perspective. Our final aim is to provide a comprehensive view of this complex region, which includes several distinct associations and dark clouds. We aim to uncover the population of the central, young star cluster Collinder 69, and in particular those diskless Class III objects not identified by previous surveys based on near- and mid-infrared searches, and to establish the X-ray luminosity function for the association.2011A&A...526A..21Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/526/A21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/118/2409 : VRI photometry of lambda Ori PMS stars (Dolan+, 1999)J/AJ/123/387 : VRI photometry of lambda Ori star-forming region (Dolan+ 2002)J/AJ/121/2124 : lambda Ori pre-main-sequence stars photometry (Dolan+, 2001)J/ApJ/610/1064 : lambda Ori substellar population (Barrado y Navascues+, 2004)J/ApJ/664/481 : Optical/IR photometry of Coll 69 (Barrado y Navascues+ 2007)J/A+A/488/167 : Low-mass stars in sigma Ori and lambda Ori (Sacco+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/526/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/526/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/526/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/526/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/526/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/526/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/526/A21/Xsources (X-ray sources detected with ML>15.0 in the EPIC observation of Collinder 69)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/526/A21/Xsources?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/526/A21/Xsources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/526/A21/Xsources?GETtext/xml+votable180.050000true83.9808339.9417220.005555555555555556Cone search capability for table J/A+A/526/A21/Osources (Optical and infrared photometry,)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/526/A21/Osources?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/526/A21/Osources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/526/A21/Osources?GETtext/xml+votable180.050000true83.980968069.942073610.0055555555555555566/23717 23719 237286.772611666688002e-21 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/526/A21?format=asciiX-rayOpticalInfrareddefaultJ/A+A/526/A21/XsourcesX-ray sources detected with ML>15.0 in the EPIC observation of Collinder 69MLMaximum likelihoodstat.likelihoodfloatrecnoRecord number assigned by the VizieR team.
