Reliable, but incomplete, source catalogue derived from UKIDSS DXS |
This view defines a reliable subset of all sources from the UKIDSS Deep eXtragalactic Survey (DXS). If your application requires a seamless selection of reliable sources in the DXS 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 dxsSource directly with appropriate predicates. If a very clean, highly reliable selection is required, then use this view. Selection is based on detecions in JK (e.g. single passband detections will NOT appear in this view). The details and SQL SELECT corresponding to this view are available here. |
