cds-question@unistra.fropen-star-clustersproper-motionsvisible-astronomyphotographic-photometryLarge-scale astrometric and photometric data bases have been used to search for and confirm stellar membership of the open cluster IC 2391. 125 stars were found that satisfied criteria for membership based on proper motion components and BRI photometry from the United States Naval Observatory B (USNO-B, Cat. <I/284>) catalogue and JHK photometry from the Two Micron All Sky Survey (2MASS, Cat. <II/246>) catalogue. This listing was compared with others recently published. A distance to the cluster of 147.7+/-5.5pc was found with mean proper motion components, from the Tycho2 catalogue of (-25.04+/-1.53mas/yr; +23.19+/-1.23mas/yr). A revised Trumpler classification of II3r is suggested. Luminosity and mass functions for the candidate stars were constructed and compared with those of field stars and other clusters.2004MNRAS.355..959Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/355/959CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/284 : The USNO-B1.0 Catalog (Monet+ 2003)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/A+A/372/862 : Lithium abundances in IC 2602 and IC 2391 (Randich+, 2001)J/ApJS/134/103 : Low-mass members of IC 2391 (Barrado y Navascues+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/355/959https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/355/959http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/355/959https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/355/959https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/355/959http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/355/959GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/355/959/table3 (Possible members of IC 2391 based on the proper motion components from the USNO-B catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/355/959/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/355/959/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/355/959/table3?GETtext/xml+votable180.050000true129.03209167-52.667019440.0055555555555555566/37785 37787-37788 37790-37791 37809 37812https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/355/959?format=asciiOpticaldefaultJ/MNRAS/355/959/table3Possible members of IC 2391 based on the proper motion components from the USNO-B cataloguerecnoRecord number assigned by the VizieR team.
