Abstract:
We present the results of a deep wide-field near-infrared survey of
the entire Pleiades cluster recently released as part of the UKIRT
Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS) Data
Release 9 (DR9). We have identified a sample of ∼1000 Pleiades
cluster member candidates combining photometry in five near-infrared
passbands and proper motions derived from the multiple epochs provided
by the UKIDSS GCS DR9. We also provide revised membership for all
previously published Pleiades low-mass stars and brown dwarfs in the
past decade recovered in the UKIDSS GCS DR9 Pleiades survey based on
the new photometry and astrometry provided by the GCS.

Note (1): Source of the object as follows:
1 = object was identified in the probabilistic approach from proper
motion (947 sources with membership probabilities≥60%, see section 4.1)
2 = object was identified with the standard photometry and proper motion
approach (section 4.2)
12 = candidate is common to both selection 1+2 methods
3 = additional lower mass member candidate (section 4.3)
