TABLE VIEW  gpsPointSource

Merged, seamless point source catalogue derived from the UKIDSS GPS

This view defines a subset of point-like sources from the UKIDSS Galactic
Plane Survey (GPS). If your science application requires a seamless
selection of sources consistently classified as point-like (i.e. stars)
in the GPS 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 reliableGpsPointSource. Detection is required 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.
