TABLE VIEW  lasPointSource

Merged, seamless point source catalogue derived from the UKIDSS LAS

This view defines a subset of point-like sources from the UKIDSS Large
Area Survey (LAS). If your science application requires a seamless
selection of sources consistently classified as point-like (e.g. stars
or QSOs) in the LAS 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 use this view since it is
optimised for reasonable completeness and NOT high reliability.
If a very clean, highly reliable but incomplete selection is sufficient,
then use view reliableLasPointSource. Detection is required in YJH;
sources appearing in one or two passbands only will not appear in this
view
The details and SQL SELECT corresponding to this view are available here.
