cds-question@unistra.frglobular-star-clustersproper-motionsWe present new blue straggler star (BSS) catalogues in 38 Milky Way globular clusters (GCs) based on multipassband and multi-epoch treasury survey data from the Hubble Space Telescope. We measure precise astrometry and relative proper motions of stars in all target clusters and performed a subsequent cluster membership selection. We study the accuracy of our proper-motion measurements using estimates of central velocity dispersions and find very good agreement with previous studies in the literature. Finally, we present a homogeneous BSS selection method, that expands the classic BSS selection parameter space to more evolved BSS evolutionary stages. We apply this method to the proper-motion cleaned GC star catalogues in order to define proper-motion cleaned BSS catalogues in all 38 GCs, which we make publicly available to enable further study and follow-up observations.2016MNRAS.462.3401Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/462/3401CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/459/489 : Blue straggler stars in open clusters (De Marchi+, 2006)J/A+A/463/789 : Blue stragglers in open clusters (Ahumada+, 2007)J/A+A/483/183 : Catalogue of Blue Stragglers (Moretti+, 2008)J/A+AS/109/375 : Blue stragglers in open clusters (Ahumada+, 1995)J/MNRAS/264/273 : CCD photometry of NGC 1261 (Ferraro+ 1993)J/A+A/516/A23 : UBVI Photometry of NGC 1261 (Kravtsov+, 2010)http://www.astro.puc.cl/~msimunov/research.html : Catalogs Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/462/3401https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/462/3401http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/462/3401https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/462/3401https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/462/3401http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/462/3401GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/462/3401/table1 (Properties of the target GC sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/462/3401/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/462/3401/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/462/3401/table1?GETtext/xml+votable180.050000true48.0675417-55.21622220.005555555555555556Cone search capability for table J/MNRAS/462/3401/catalog (Proper-motion cleaned blue straggler star (BSS) catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/462/3401/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/462/3401/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/462/3401/catalog?GETtext/xml+votable180.050000true48.0822474-55.22597940.0055555555555555566/9666 10321 12425 12943 19091 24843 27975 27981 27984 27986 28741 28751 28959 28973 29184 30378 30769 30995 30998 31019 31115 33635 34242 38465 41257 41304 41522 41852 42278 42314 42955 42958 43125 47620 47777 47825 47866 47868 47971 48434 489522.76124552865182e-19 3.9057996558789745e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/462/3401?format=asciidefaultJ/MNRAS/462/3401/table1Properties of the target GC samplerecnoRecord number assigned by the VizieR team.
