Reliable, but incomplete, point source catalogue derived from UKIDSS GPS |
This view defines a reliable subset of point-like sources from the UKIDSS Galactic Plane Survey (GPS). If your application requires a seamless selection of reliable 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 gpsPointSource since it is optimised for completeness and NOT high reliability. If a very clean, highly reliable selection is required, then use this view. Because reliability is optimised over completeness here, discrete classification codes are used as these are conservative in flagging ojects as point-like. The selection is based on stellar 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. |
