| Cross-neighbours between dxsSource and the 2MASS point source catalogue. |
| All 2MASS point sources within 15 arcsec of each merged source from UKIDSS DXS data are recorded in this cross-neighbour table. The table dxsSource was joined to the wise_prelimsc table to create these cross-neighbours. Use this table for any cross-querying of UKIDSS DXS data with point sources from 2MASS. |
