cds-question@unistra.fropen-star-clustersinfrared-photometryWe present here exhaustive lists of known young stars and new candidate members around Alnilam and Mintaka in the Ori OB1b association as well as of fore- and background sources. A total of 133 stars display features of extreme youth, including early spectral types, lithium in absorption, or mid-infrared flux excess. Other two young brown dwarf and 289 star candidates have been identified from an optical/near-infrared colour-magnitude diagram. We list additional 74 known objects that might belong to the association. This compilation of tables can serve as an input for characterisation of the stellar and high-mass substellar populations in the Orion Belt.2008A&A...485..931Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/485/931CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/485/931https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/485/931http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/485/931https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/485/931https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/485/931http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/485/931GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/485/931/phot (Photometry of correlated Tycho-2/2MASS sources in the 2 fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/phot?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/phot?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/phot?GETtext/xml+votable180.050000true83.9373961-1.934390.005555555555555556Cone search capability for table J/A+A/485/931/members (Tycho and 2MASS data for knwon young stars in Tycho-2/2MASS catalogues)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/members?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/members?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/members?GETtext/xml+votable180.050000true83.8132083-1.90211110.005555555555555556Cone search capability for table J/A+A/485/931/unknown (Tycho and 2MASS data for foreground or background stars, of stars with unknown association status)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/unknown?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/unknown?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/unknown?GETtext/xml+votable180.050000true83.8869583-1.84613890.005555555555555556Cone search capability for table J/A+A/485/931/new (Known, new young stars and stars of unknown status in DENIS/2MASS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/new?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/new?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/new?GETtext/xml+votable180.050000true84.1087083-1.6630.005555555555555556Cone search capability for table J/A+A/485/931/tablea12 (Fore- and background objects in the Alnilam and Mintaka fields and in DENIS/2MASS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/tablea12?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/tablea12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/tablea12?GETtext/xml+votable180.050000true84.46825-1.46033330.005555555555555556Cone search capability for table J/A+A/485/931/tablea13 (Probable reddened stars in DENIS/2MASS associated to remnant molecular clouds in the Alnilam and Mintaka fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/tablea13?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/tablea13?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/tablea13?GETtext/xml+votable180.050000true84.519875-1.75894440.005555555555555556Cone search capability for table J/A+A/485/931/2masx (Galaxies in 2MASX })https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/2masx?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/2masx?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/2masx?GETtext/xml+votable180.050000true83.971-1.94708330.005555555555555556Cone search capability for table J/A+A/485/931/denis (Galaxies in DENIS })https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/denis?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/denis?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/denis?GETtext/xml+votable180.050000true84.128-1.89552780.005555555555555556Cone search capability for table J/A+A/485/931/tablea18 (Remarkable fore- and background objects in the comparison fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/485/931/tablea18?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/485/931/tablea18?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/485/931/tablea18?GETtext/xml+votable180.050000true92.33225-21.07672220.0055555555555555565/5715 5721 6/20898 20903-20905 20909 20922 21272 21285 21287 21297 21302 21308 22857 22859 22881 22893 22895 22899 229048.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/485/931?format=asciiInfrareddefaultJ/A+A/485/931/photPhotometry of correlated Tycho-2/2MASS sources in the 2 fieldsrecnoRecord number assigned by the VizieR team.
