We compare UBVRI photometric observations of eleven YOCs to theoretical isochrones in the photometric diagrams. The comparison simultaneously provides membership assignments for MS and PMS stars and estimates for the masses, ages, and spatial distribution of the candidate members. The relations found between the different cluster parameters show that the procedure applied to assign cluster membership, and to measure physical parameters for the selected members, is well founded.2011A&A...531A.141Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/531/A141CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/531/A141https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/531/A141http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/531/A141https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/531/A141https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/531/A141http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/531/A141GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/531/A141/table1 (Clusters observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/531/A141/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/531/A141/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/531/A141/table1?GETtext/xml+votable180.050000true110.0494-21.93020.005555555555555556Cone search capability for table J/A+A/531/A141/catalog (Photometric results and physical parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/531/A141/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/531/A141/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/531/A141/catalog?GETtext/xml+votable180.050000true109.607625-25.035701940.0055555555555555566/37333 37926 38016 38018 38024 39907 39930 41646 41856 43042 430483.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/531/A141?format=asciiOpticalInfrareddefaultJ/A+A/531/A141/table1Clusters observedrecnoRecord number assigned by the VizieR team.
