This is part of a program to follow the evolution of protoplanetary accretion disks through the ages thought to be crucial to understanding disk dissipation and planet formation (~3-10Myr). Combining optical photometry and optical spectroscopy, we have identified ~40 members in Tr37 and ~15 in NGC7160, using several independent tests for determining the membership (optical colors, optical variability, H{alpha} emission, and Li{lambda}6707 absorption).2004AJ....128..805Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/128/805CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/128/805https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/128/805http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/128/805https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/128/805https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/128/805http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/128/805GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/128/805/NGC7160 (NGC 7160 spectral data, extinction, membership and photometry (tables 3 and 7 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/805/NGC7160?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/805/NGC7160?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/805/NGC7160?GETtext/xml+votable180.050000true327.87187562.58380560.005555555555555556Cone search capability for table J/AJ/128/805/Tr37 (Tr 37 spectral data, extinction, membership and photometry (tables 2 and 6 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/805/Tr37?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/805/Tr37?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/805/Tr37?GETtext/xml+votable180.050000true324.20587557.52286110.0055555555555555566/15478 15479 15662 15663 15748 157498.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/128/805?format=asciiOpticalInfrareddefaultJ/AJ/128/805/NGC7160NGC 7160 spectral data, extinction, membership and photometry (tables 3 and 7 of paper)recnoRecord number assigned by the VizieR team.
