cds-question@unistra.fropen-star-clustersinfrared-photometryproper-motionsPresented are the results of a large and deep optical-near-infrared multi-epoch survey of the Praesepe open star cluster using data from the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey. Multiple colour-magnitude diagrams were used to select potential members and proper motions were used to assign levels of membership probability. From our sample, 145 objects were designated as high probability members (p>=0.6) with most of these having been found by previous surveys although 14 new cluster members are also identified. Our membership assignment is restricted to the bright sample of objects (Z<18). From the fainter sample, 39 candidates were found from an examination of multiple colour-magnitude plots.2010MNRAS.408.2457Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/408/2457CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/124/1570 : JHKs photometry in Praesepe (Adams+, 2002)J/AJ/134/2340 : Membership of Praesepe & Coma Berenices clusters (Kraus+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/408/2457https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/408/2457http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/408/2457https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/408/2457https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/408/2457http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/408/2457GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/408/2457/members (High-probability Praesepe low-luminosity members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/408/2457/members?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/408/2457/members?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/408/2457/members?GETtext/xml+votable180.050000true128.94112522.51166670.005555555555555556Cone search capability for table J/MNRAS/408/2457/tabled1 (SDSS-UKIDSS selected candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/408/2457/tabled1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/408/2457/tabled1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/408/2457/tabled1?GETtext/xml+votable180.050000true130.57612521.39502780.0055555555555555565/1175 1177 1180 6/4675 4677-4678 4681 4683-4684 4686-4688 4694-4695 4697-4699 4705 4716-4717 4724-4726 4728-4729 47328.305533028865447e-20 2.3717893470513554e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/408/2457?format=asciiInfrareddefaultJ/MNRAS/408/2457/membersHigh-probability Praesepe low-luminosity membersAD?
