cds-question@unistra.fropen-star-clustersstellar-populationsWe present a new high-mass membership of the nearby Sco OB2 association based on Hipparcos positions, proper motions and parallaxes, and radial velocities taken from the 2nd Catalogue of Radial Velocities with Astrometric Data (CRVAD-2). The Bayesian membership selection method developed makes no distinction between subgroups of Sco OB2 and utilizes linear models in calculation of membership probabilities. We select 436 members, 88 of which are new members not included in previous membership selections. We include the classical non-members alpha-Cru and beta-Cru as new members as well as the pre-main-sequence stars HIP 79080 and 79081. We also show that the association is well mixed over distances of 8{deg} on the sky, and hence no determination can be made as to the formation process of the entire association.2011MNRAS.416.3108Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/416/3108CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/254 : 2nd Cat. of Radial Vel. with Astrometric Data (Kharchenko+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/416/3108https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/416/3108http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/416/3108https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/416/3108https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/416/3108http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/416/3108GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/416/3108/tablea1 (Membership list and probabilities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/3108/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/3108/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/3108/tablea1?GETtext/xml+votable180.050000true154.7711356-64.67625780.0055555555555555565/10746 11079 6/24613 24629 29219 29320 29348 29358 30722-30723 37149 37186 37197 37236-37237 37242 37268 37314 37888 37905 37928 37953 37956 37968 37973 37978 37990 38023 38084 38145-38146 38157 38162 38212 38215 38255 38272 41513 41534 41606-41607 41632 41634 41637 41643 41652 41657 41661 41677 41682 41704-41705 41707 41710 41726 41815 41866 41869 41900 41906 41917-41918 41943 41946-41947 41963 41973 41983 42174 42382 42400 42406-42407 42412 42416 42419 42425 42428 42466 42509 42549 42559 42563 42584-42585 42605 42610-42613 42617-42619 42622-42623 42631 42640 42645 42649 42651-42652 42654-42655 42658 42670 42672 42674 42676-42678 42684 42687-42688 42694 42696 42701 42707-42709 42711 42714 42725 42727-42728 42730 42734 42736 42738 42746 42749 42754 42757 42763 42778 42782 42800 42808 42811 42819 42848 42857-42858 42873 42875-42876 42892 42896 42909 42911-42913 42916-42917 42924 42928 42932 42934 42940-42941 42943 42948 42953 42955 42959 42972 42977-42978 42980 42989-42991 42994 43002 43011-43012 43014 43017 43019 43021 43029 43035 43037-43038 43054-43055 43057 43059 43062 43065 43067 43072-43073 43085 43093-43094 43097 43101 43103 43111 43115 43117 43127 43130 43133 43137-43140 43147 43150 43153-43154 43157 43160-43161 43166 43168-43169 43177 43182-43183 43192 43196-43197 43201 43205-43206 43208 43210-43211 43224-43225 43228-43230 43232 43238-43239 43244 43246 43255-43256 43259 43272 43274 43276-43277 43279 43285 43292-43293 43298 43323 43326 43331 43338 43342 43345 43349 43360-43361 43364-43365 43367 43369 43372 43375 43377-43378 43383 43397 43402-43403 43407 43414 43416 43423 43425 43429 43435 43460 43469 43474 43488 43492 43505 43507 43521-43523 43527 43529-43531 43538 43540 43557-43558 43564 43603-43604 43677 43683 43700 43716 43764 43843 43910 44043-44044 44046 44049 44052 44054 44059 44069 44076 44081 44085-44086 44088 44093 44096 44098 44101 44106 44114 44119 44132-44133 44136 44139 44146 44156 44165 44178 44204 44213 44238 44293 44301 44306-44308 44312-44314 44321 44329 44341 44352-44354 44356 44359-44361 44363 44366 44368 44371 44377-44378 44384 44389 44400 44403 44409 44421 44436 44469 44480 44502https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/416/3108?format=asciiOpticaldefaultJ/MNRAS/416/3108/tablea1Membership list and probabilitiesHIPHipparcos numbermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
