GES spectroscopy and Gaia astrometry from its second data release are used here to assign membership probabilities to targets towards 32 open clusters with ages from 1 to 3800Myr, based on maximum likelihood modelling of the 3D kinematics of the cluster and field populations. From a parent catalogue of 14398 individual targets, 5032 stars with uniformly determined 3D velocities, T_eff_, log g, and chemistry are assigned cluster membership with probability >0.9, and with an average probability of 0.991. The robustness of the membership probabilities is demonstrated using independent membership criteria (lithium and parallax) in two of the youngest clusters. The addition of radial velocities improves membership discrimination over proper motion selection alone, especially in more distant clusters. The kinematically selected nature of the membership lists, independent of photometry and chemistry, makes the catalogue a valuable resource for testing stellar evolutionary models and investigating the time evolution of various parameters.2020MNRAS.496.4701Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/496/4701CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+A/612/A99 : Gaia-ESO Survey in 7 open star cluster fields (Randich+, 2018)J/A+A/566/A50 : Classification of stellar spectra 644-681nm (Damiani+, 2014)J/A+A/563/A94 : Kinematics of the Gamma Vel cluster (Jeffries+, 2014)J/A+A/580/A75 : Velocity precision in the Gaia-ESO Survey (Jackson+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/496/4701https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/496/4701http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/496/4701https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/496/4701https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/496/4701http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/496/4701GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/496/4701/table1 (Cluster data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/496/4701/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/496/4701/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/496/4701/table1?GETtext/xml+votable180.050000true160.986-59.5530.005555555555555556Cone search capability for table J/MNRAS/496/4701/table2 (Gaia-ESO Survey data used to estimate the probability of cluster membership for targets observed in the 32 clusters of Table 1)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/496/4701/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/496/4701/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/496/4701/table2?GETtext/xml+votable180.050000true160.75254-59.52950.0055555555555555565/4122 5514 5934 9239 9282 9307 9329 9398 9838 9924 6/4783 6148-6149 14336 16447 16576-16577 20562 22432-22433 23636-23637 23639 23695 23717 23719 23728 23730 28822-28823 28889-28891 30215 30226 30308 31785 31787-31788 31790 31809 31812 32089 36947 36950 36953 36955 37122-37123 37225 37227 37240-37242 37313 37333 37586-37587 37785 37787-37788 37790 37809 37812 38016 39181 39183 39192 39194 39205 39216-39218 39358 39685 41466 41649 41678 42153 42156 42374 42380 42496 42959 42980-42981 42983 42992 42994 430347.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/496/4701?format=asciiOpticaldefaultJ/MNRAS/496/4701/table1Cluster datar_AgeReference for Agemeta.ref;pos.frameints_mumembStatistical uncertainty on mumembmagstat.error;phot.magfloate_mumembSystematic uncertainty on mumemb corresponding to +/-0.1mas in parallaxmagstat.errorfloatE(B-V)membMean reddening determined from high-probability cluster membersmagphot.color.excessfloate_E(B-V)membError on E(B-V)membmagstat.errorfloat_RARight Ascension (J2000) from SIMBAD (not part of the original data)degpos.eq.ra;meta.main_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
