| Cross-neighbours between atlas and rosat_fsc. | 
|  All ROSAT-ASS sources within 30.0 arcsec of each source from ATLAS data are recorded in this cross-neighbour table. The table atlasSource was joined to the rosat_fsc table to create these cross-neighbours. Use this table for any cross-querying of ATLAS data with sources from ROSAT-ASS.  |
