cds-question@unistra.fropen-star-clusterspre-main-sequence-starsphotometryline-intensitiesWe present a wide-field photometric survey covering ~200^{deg}^2 toward the Upper Scorpius OB association. Data taken in the R and I bands with the Quest-2 camera on the Palomar 48inch (1.2m) telescope were combined with the Two Micron All Sky Survey JHK_S_ survey and used to select candidate pre-main-sequence stars. Follow-up spectroscopy with the Palomar 200inch (5.1m) telescope of 62 candidate late-type members identified 43 stars that have surface gravity signatures consistent with association membership.2006AJ....131.3016Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/3016CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/120/479 : Low-mass stars in the Upper Sco association (Ardila+, 2000)J/A+A/333/619 : Upper Scorpius OB association Lithium survey (Preibisch+ 1998)J/AJ/121/1040 : PMS members of upper Scorpius OB association (Preibisch+ 2001)J/AJ/124/404 : Upper Scorpius OB association Lithium survey.
