cds-question@unistra.fropen-star-clustersinfrared-photometryproper-motionsWe present the results of a deep (J=19.1mag) infrared (ZY JHK) survey over the full {alpha} Per open cluster extracted from the Data Release 9 of the United Kingdom Infrared Telescope Infrared Deep Sky Survey Galactic Clusters Survey (UKIDSS). We have selected ~700 cluster member candidates in ~56 square degrees in {alpha} Per by combining photometry in five near-infrared passbands and proper motions derived from the multiple epochs provided by the UKIDSS Galactic Clusters Survey (GCS) Data Release 9 (DR9). We also provide revised membership for all previously published {alpha} Per low-mass stars and brown dwarfs recovered in GCS based on the new photometry and astrometry provided by DR9.2012MNRAS.426.3403Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/426/3403CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)J/A+A/436/853 : IR photometry of alpha Per low-mass members (Lodieu+, 2005)J/AN/319/201 : alpha Per cluster low-mass members.
