The WFCAM Science Archive (WSA) holds the image and catalogue data products generated by the Wide Field Camera (WFCAM) on UKIRT. There are are three components
to the databases provided here. (1) The UKIRT InfraRed Deep Sky Surveys (UKIDSS): Large Area Survey, Galactic Plane Survey, Galactic Clusters Survey, Deep Extragalactic Survey and the
Ultra Deep Survey. (2) The UKIRT Hemisphere Survey (UHS). (3) Non-survey data, belonging to individual PIs.

SUM_FLAG
The summary flag of the source is derived from EP_FLAG. It is 0 if none of the nine flags was set; it is set to 1 if at least one of the warning flags (flag 1, 2, 3, 9) was set but no possible-spurious-detection flag (flag 7, 8); it is set to 2 if at least one of the possible-spurious-detection flags (flag 7, 8) was set but not the manual flag (flag 11); it is set to 3 if the manual flag (flag 11) was set but no possible-spurious-detection flags (flag 7, 8); it is set to 4 if the manual flag (flag 11) as well as one of the possible-spurious-detection flags (flag 7, 8) is set. The meaning is thus: 0 = good, 1 = source parameters may be affected, 2 = possibly spurious, 3 = located in a area where spurious detection may occur, 4 = located in a area where spurious detection may occur and possibly spurious. .

The co-sigma of the equatorial position uncertainties, sig_ra, sig_dec (σ<sub>α</sub>, σδ<sub></sub>). The co-sigma is related to the covariance between the position errors Vαδ by the formula Vαδ = σ<sub>αδ</sub>×|σ<sub>αδ</sub>|. This maintains the sign information for the correlation, since σ<sub>αδ</sub> may be negative. It is more natural to carry the co-sigma along with the other uncertainties instead of the covariance because the former is in the same units as the other uncertainties.
