TABLE VIEW  reliableDxsSource

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.
