The eleventh Data Release of the UKIRT InfraRed Deep Sky Surveys (UKIDSS) from the WFCAM Science Archive (WSA) generated by the Wide Field Camera (WFCAM) on the United Kingdom Infrared Telescope (UKIRT) contains five surveys:

  • Large Area Survey (LAS)
  • Galactic Plane Survey (GPS)
  • Galactic Clusters Survey (GCS)
  • Deep Extragalactic Survey (DXS)
  • Ultra Deep Survey (UDS)
Each of the five surveys have been crossmatched against five other Data Lab datasets:

The UKIDSS source tables were provided by the WIde Field Astronomy Unit (WFAU) of the University of Edinburgh and originate from UKIDSS DR11 of the WFCAM science archive (Hambly et al (2008, MNRAS, 384, 637)).
The UKIDSS project is defined in Lawrence et al 2007 (MNRAS, 379, 1599). UKIDSS uses the UKIRT Wide Field Camera (WFCAM; Casali et al 2007, A&A, 467, 777) and a photometric system described in Hewett et al 2006 (MNRAS, 367, 454).

Note that we have added the following columns to each of the five tables to improve usability within Data Lab:

  • elat
  • htm9
