cds-question@unistra.frsurveysquasarsinfrared-photometryvisible-astronomysloan-photometryWe present a catalog of over 130000 quasar candidates with near-infrared (NIR) photometric properties, with an areal coverage of approximately 1200deg^2^. This is achieved by matching the Sloan Digital Sky Survey (SDSS) in the optical ugriz bands to the UKIRT Infrared Digital Sky Survey (UKIDSS) Large Area Survey (LAS) in the NIR YJHK bands. We match the ~1 million SDSS DR6 Photometric Quasar catalog to Data Release 3 of the UKIDSS LAS (ULAS) and produce a catalog with 130827 objects with detections in one or more NIR bands, of which 74351 objects have optical and K-band detections and 42133 objects have the full nine-band photometry.2011AJ....141..105Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/105CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/310 : UKIDSS-DR7 Large
