Reliable, but incomplete, source catalogue derived from UKIDSS UDS |
This view defines a reliable subset of all sources from the UKIDSS Ultra Deep Survey (UDS). If your application requires a selection of reliable sources in the UDS then use this view. NB: as always, there is a trade-off between completeness and reliability. If completeness is more important than high reliability, then make your sample selection from udsSource directly with appropriate predicates. If a very clean, highly reliable selection is required, then use this view. Selection is based on detecions in JHK (e.g. single passband detections will NOT appear in this view). The details and SQL SELECT corresponding to this view are available here. |
