| Cross-neighbours between atlas and twomass_xsc. |
| All TWOMASS..twomass_xsc sources within 10.0 arcsec of each source from ATLAS data are recorded in this cross-neighbour table. The table atlasSource was joined to the twomass_xsc table to create these cross-neighbours. Use this table for any cross-querying of ATLAS data with sources from 2MASS. |
