cds-question@unistra.frmilky-way-galaxyopen-star-clustersstellar-populationsvisible-astronomyThe Li abundance observed in pre-main sequence and main sequence late-type stars is strongly age-dependent, but also shows a complex pattern depending on several parameters, such as rotation, chromospheric activity, and metallicity. The best way to calibrate these effects, and with the aim of studying Li as an age indicator for FGK stars, is to calibrate coeval groups of stars, such as open clusters (OCs) and associations. We present a considerable target sample of 42 OCs and associations - with an age range from 1Myr to 5Gyr - observed within the Gaia-ESO survey (GES), and using the latest data provided by GES iDR6 and the most recent release of Gaia that was then available, EDR3. As part of this study, we update and improve the membership analysis for all 20 OCs presented in our previous article. We perform detailed membership analyses for all target clusters to identify likely candidates, using all available parameters provided by GES, complemented with detailed bibliographical searches, and based on numerous criteria: from radial velocity distributions, to the astrometry (proper motions and parallaxes) and photometry provided by Gaia, to gravity indicators (logg and the gamma index), [Fe/H] metallicity, and Li content in diagrams of EW(Li) (Li equivalent widths) versus Teff. We obtain updated lists of cluster members for the whole target sample, as well as a selection of Li-rich giant contaminants obtained as an additional result of the membership process. Each selection of cluster candidates was thoroughly contrasted with numerous existing membership studies using data from Gaia to ensure the most robust results. These final cluster selections will be used in the third and last paper of this series, which reports the results of a comparative study characterising the observable Li dispersion in each cluster and analysing its dependence on several parameters, allowing us to calibrate a Li-age relation and obtain a series of empirical Li envelopes for key ages in our sample.2024A&A...685A..83Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/685/A83CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/643/A71 : Members for 20 open clusters (Gutierrez Albarran+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/685/A83https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/685/A83http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/685/A83https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/685/A83https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/685/A83http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/685/A83GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/685/A83/clusters (List of studied clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/685/A83/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/685/A83/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/685/A83/clusters?GETtext/xml+votable180.050000true271.1291667-24.35833330.005555555555555556Cone search capability for table J/A+A/685/A83/tablec1 (GES parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/685/A83/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/685/A83/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/685/A83/tablec1?GETtext/xml+votable180.050000true270.634-24.23466670.0055555555555555565/4122 5514 5934 9239 9282 9307 9329 9398 9838 9924 6/4298 14336 16447 16576-16577 20562 21557 22224-22225 22249 22252 22498-22499 23636-23637 23639 23695 23704-23706 23717 23719 23728 23730 28806-28807 28812-28813 28889-28891 29523 30215 30226 30308 30311 30635 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 37933 37938 37944 38016 38441 39181 39183 39192 39194 39205 39216-39218 39257 39259 39350 39356 39358 39685 41466-41467 41649 41678 42153 42156 42374 42380 42464 42496 42959 42980-42981 42983 42992 42994 43034https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/685/A83?format=asciiOpticaldefaultJ/A+A/685/A83/clustersList of studied clustersrecnoRecord number assigned by the VizieR team.
