WSA - WFCAM Science Archive

The WFCAM Science Archive (WSA) holds the image and catalogue data products generated by the Wide Field Camera (WFCAM) on UKIRT. The primary contents of the archive will originate from the UKIRT InfraRed Deep Sky Surveys (UKIDSS): Large Area Survey, Galactic Plane Survey, Galactic Clusters Survey, Deep Extragalactic Survey and the Ultra Deep Survey.

Survey data is being released in phases, firstly to the UKIDSS community and then to the public (see data policy).

The latest UKIDSS release is UKIDSS data release 6 (UKIDSSDR6PLUS)
The latest WORLD release is UKIDSS data release 4 (UKIDSSDR4PLUS) for all surveys except the GPS
(Note: world users please use UKIDSSDR3PLUS for the GPS)

Information on the various archive releases can be found on the surveys page

The history of archive releases, updates and bug fixes is recorded under the release history page. Users wishing to receive email announcements of such entries should subscribe to the WSA_Announcelist (contact wsa-support@roe.ac.uk).

Picture: Early Commissioning - Central region of a full tile, showing dramatic clouds of gas and dust illuminated by stars in the southern half of the Orion nebula. This is an image at three infrared wavelengths (red represents narrow-band emission from molecular hydrogen gas at 2.12 microns, green represents K-band emission at 2.2 microns, and blue represents J-band emission at 1.25 microns).
