Cross-neighbours between udsSource and 2XMM sources. |
All 2XMM point sources within 15 arcsec of each merged source from UKIDSS UDS data are recorded in this cross-neighbour table. The table udsSource was joined to the XMM..twoxmm table to create these cross-neighbours. Use this table for any cross-querying of UKIDSS UDS data with the second XMM serendipitous source pre-release catalogue (2XMM). |
