Combining our own speckle-interferometric observations with data taken from the literature, we found a ratio of the number of single to multiple stars to be 29:8:0:0:0:1 for the most probable members, indicating a multiplicity fraction for this cluster of 25.6%+/-2%. We also observed field stars in the vicinity of the cluster and estimated a ratio of multiplicities of 286:17:1:0:0:0:1 (between one and seven companions), equivalent to a multiplicity fraction of 5.9%+/-3%. We showed that the cumulative distribution of separations for our sample stars is in agreement with Opik's law.2015AJ....150...16Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/150/16CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)I/280 : All-sky Compiled Catalogue of 2.5 million stars (Kharchenko+ 2009)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)J/AJ/141/45 : Speckel observations of HIP stars (Horch+, 2011)J/A+A/491/951 : Positions and cross-references in Coma Ber (Mermilliod+ 2008)J/A+A/438/1163 : Catalogue of Open Cluster Data (COCD) (Kharchenko+, 2005)J/AN/325/740 : Astrophysical supplements to ASCC-2.5 (Kharchenko+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/150/16https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/150/16http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/150/16https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/150/16https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/150/16http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/150/16GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/150/16/table4 (R photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/16/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/16/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/16/table4?GETtext/xml+votable180.050000true181.0697247228.157970.005555555555555556Cone search capability for table J/AJ/150/16/table1 (Known stellar multiplicity)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/16/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/16/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/16/table1?GETtext/xml+votable180.050000true181.8359211127.539675280.005555555555555556Cone search capability for table J/AJ/150/16/table2 (Known spectroscopic binaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/16/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/16/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/16/table2?GETtext/xml+votable180.050000true185.6263002825.846159440.005555555555555556Cone search capability for table J/AJ/150/16/table3 (Speckle measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/150/16/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/150/16/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/150/16/table3?GETtext/xml+votable180.050000true185.1698547227.053510.0055555555555555564/1777 1780 5/7023 7032 7034 7035 7038 7124 7128 6/28085 28086 28087 28089 28090 28091 28105 28106 28107 28132 28134 28135 28421 28422 28423 28468 28469 28471 28500 28502 28504 28505 28516 28517 28520 285212.762881831355591e-19 3.3785437584409506e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/150/16?format=asciiOpticalInfrareddefaultJ/AJ/150/16/table4R photometryrecnoRecord number assigned by the VizieR team.
