cds-question@unistra.frinfrared-photometryvisible-astronomyphotometrystellar-massesCoordinates and photometry of very low mass objects near epsilon Ori are presented. The RIJHK photometry of these objects is consistent with membership of the young Ori OB Ib association. Time series observations of this region were carried out using the ESO/MPG WFI at the 2.2-m telescope on La Silla, from 18 to 22 December 2001. In the framework of this monitoring campaign, we obtained deep Cousins R- and I-band images, from which we derived coordinates (columns 2 and 3) as well as photometry in the R- and I-band (columns 4 and 5). Additional near-infrared photometry in J, H, K comes from the 2MASS database (columns 6--8). The cluster member selection is based on a (I,R-I) colour magnitude diagram. The (J-H) colours were used to reject contaminating field stars. The masses given in column 9 were estimated by comparing the near-infrared photometry with the evolutionary tracks of Baraffe et al. (1998A&A...337..403B), assuming an age of 5Myr.2005A&A...429.1007Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/429/1007CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/429/1007https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/429/1007http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/429/1007https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/429/1007https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/429/1007http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/429/1007GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/429/1007/table2 (RIJHK photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/429/1007/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/429/1007/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/429/1007/table2?GETtext/xml+votable180.050000true83.4300833-0.64927220.0055555555555555566/22862-22863 22884-228858.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/429/1007?format=asciiOpticalInfrareddefaultJ/A+A/429/1007/table2RIJHK photometryKsmagKs-band photometry (from 2MASS)magfloatrecnoRecord number assigned by the VizieR team.
