cds-question@unistra.fropen-star-clustersx-ray-sourcesWe present the results of a 47-ks Chandra/ACIS observation of the old open cluster M67. We detected 25 proper-motion cluster members (including ten new sources) and 12 sources (all new) that we suspect to be members from their locations close to the main sequence (1<B-V<1.7). Of the detected members, 23 are binaries.2004A&A...418..509Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/418/509CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/52 : Photometry and Proper Motions in M67 (Frolov+ 1986)II/123 : UBV Photometry of Faint Stars (V>14.5) in M67 (Frolov+ 1986)J/AJ/106/181 : CCD photometry of open cluster M67 (Montgomery+ 1993)J/AJ/112/628 : BATC Color Survey of M67 (Fan+ 1996)J/A+A/382/899 : BVI photometry in M67 (Stassun+, 2002)J/BaltA/7/369 : M67 CCD photometry (Boyle+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/418/509https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/418/509http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/418/509https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/418/509https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/418/509http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/418/509GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/418/509/table1 (Catalogue of Chandra sources in the field of M67)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/418/509/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/418/509/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/418/509/table1?GETtext/xml+votable180.050000true132.8057208311.8611750.005555555555555556Cone search capability for table J/A+A/418/509/table4 (Estimated positions of faint optical counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/418/509/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/418/509/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/418/509/table4?GETtext/xml+votable180.050000true132.737916711.76880560.005555555555555556Chandra6/4298https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/418/509?format=asciiX-raydefaultJ/A+A/418/509/table1Catalogue of Chandra sources in the field of M67HR?
