UKIDSS is a set of five surveys. The 2010 revised final areas and 5-sigma depths are as follows:
|1.||Large Area Survey (LAS)||3792 sq. degs||K=18.2||extraGalactic|
|2.||Galactic Plane Survey (GPS)||1851 sq. degs||K=18.6||Galactic|
|3.||Galactic Clusters Survey (GCS)||1069 sq. degs||K=18.6||Galactic|
|4.||Deep Extragalactic Survey (DXS)||31 sq. degs||K=20.8||extraGalactic|
|5.||Ultra Deep Survey (UDS)||0.77 sq. degs||K=22.8||extraGalactic|
The surveys will use 1000 nights of UKIRT time over 7 years, beginning in April 2005. The pages for each survey provide details of the filters, depths, areas, and targets. Each page summarises the overall 7-year plan as well as the plan for the first 2 years. The 7-year plans may change somewhat as the surveys progress. The 2-year plans have been worked up in detail and are now essentially fixed. The figure below shows the 7-year UKIDSS sky coverage.
