cds-question@unistra.fropen-star-clustersproper-motionsinfrared-photometrystellar-massesWe have determined possible cluster members of the nearby open cluster Praesepe (M44) based on J and K photometry and proper motions from the PPMXL catalogue and z photometry from the Sloan Digital Sky Survey. In total, we identified 893 possible cluster members down to a magnitude of J=15.5mag, corresponding to a mass of about 0.15M_{sun}_ for an assumed cluster distance modulus of (m-M)0=6.30mag (d~182pc), within a radius of 3.5{deg} around the cluster centre. We derive a new cluster centre for Praesepe (RA_centre_=8:39:37, DE_centre_=19:35:02). We also derive a total cluster mass of about 630M_{sun}_, and a 2D half-number and half-mass radius of 4.25 and 3.90pc, respectively.2013MNRAS.434.3236Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/434/3236CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/257 : Proper Motions in Praesepe (Wang+, 1995)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)I/317 : PPMXL Catalog (Roeser+ 2010)V/139 : SDSS Photometric Catalog, DR 9 (Adelman-McCarthy+, 2012)VII/233 : 2MASS Extended sources (IPAC/UMass, 2003-2006)J/AJ/134/2340 : Membership of Praesepe & Coma Berenices clustersJ/MNRAS/426/3419 : UKIDSS GCS Praesepe members (Boudreault+, 2012)J/MNRAS/442/2081 : Praesepe members light curves (Kovacs+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/434/3236https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/434/3236http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/434/3236https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/434/3236https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/434/3236http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/434/3236GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/434/3236/table2 (Celestial coordinates, proper motions, magnitudes and the masses of the possible members of Praesepe sorted by right ascension)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/434/3236/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/434/3236/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/434/3236/table2?GETtext/xml+votable180.050000true126.4233988919.511820.0055555555555555565/1169 1171-1172 1174-1175 1177 1180-1181 6/4346 4681-4683 4692 4694-4695 4705 4707 4713 4716-4717 4728-4730 4732 4872 4874 48968.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/434/3236?format=asciiInfrareddefaultJ/MNRAS/434/3236/table2Celestial coordinates, proper motions, magnitudes and the masses of the possible members of Praesepe sorted by right ascensionMassMass (2)solMassphys.massfloatrecnoRecord number assigned by the VizieR team.
