| Merged, seamless extended source catalogue derived from the UKIDSS LAS |
| This view defines a subset of extended sources from the UKIDSS Large Area Survey (LAS). If your science application requires a seamless, reliable selection of sources consistently classified as extended in the LAS (e.g. galaxies) then use this view. Detection is required in all bands except Y, and selection is based on discrete classification codes "Galaxy" (+1) or "Probable Galaxy" (-3). |
