| Cross-neighbours between lasSource and the 2MASS extended source catalogue. |
| All 2MASS point sources within 20 arcsec of each merged source from UKIDSS LAS data are recorded in this cross-neighbour table. The table lasSource was joined to the twomass_xsc table to create these cross-neighbours. Use this table for any cross-querying of UKIDSS LAS data with extended sources from 2MASS. |
