cds-question@unistra.fropen-star-clustersinfrared-photometryline-intensitiesWe have used the Two Micron All Sky Survey and Palomar Observatory Sky Survey photographic plates, digitized by the US Naval Observatory's Precision Measuring Machine program, to derive proper motions over a 100 square degree, spatially complete region centered on the Praesepe open cluster. Proper-motion measurements spanned the magnitude range R~12-19, which covers most of the lower main sequence in Praesepe. The incidence of H{alpha} emission from moderate-resolution (~2600), red spectroscopy of 434 faint candidate members and 126 field control stars demonstrates that ~60%-80% of candidates within 2{deg} of the cluster center are genuine Praesepe members.2002AJ....124.1570Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/124/1570CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/2mass : The 2MASS database (IPAC/UMass, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/124/1570https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/124/1570http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/124/1570https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/124/1570https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/124/1570http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/124/1570GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/124/1570/table1 (Data for sources in Praesepe's region of the vector point diagram in Figure 3)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/124/1570/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/124/1570/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/124/1570/table1?GETtext/xml+votable180.050000true123.6526969419.532163890.005555555555555556Cone search capability for table J/AJ/124/1570/table6 (Data for all field control stars observed with the WIYN telescope, at Kitt Peak Observatory)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/124/1570/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/124/1570/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/124/1570/table6?GETtext/xml+votable180.050000true128.7421119420.001611940.005555555555555556Cone search capability for table J/AJ/124/1570/table5 (Data for all Praesepe candidates observed with the WIYN telescope, at Kitt Peak Observatory)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/124/1570/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/124/1570/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/124/1570/table5?GETtext/xml+votable180.050000true128.73083520.184473060.0055555555555555563/73 5/1083 1086-1087 1157 1159 1165 1201 1204-1205 1216 1218-1219 1224-1226 6/4287 4323 4326-4327 4329-4331 4338-4339 4342-4343 4520 4522-4523 4668-4669 4671 4757 4800-4801 4803 4812-4813 4824-4825 4828-4829 4868 4870 4908 4910 4992-49948.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/124/1570?format=asciiInfrareddefaultJ/AJ/124/1570/table1Data for sources in Praesepe's region of the vector point diagram in Figure 3recnoRecord number assigned by the VizieR team.
