TABLE  CrossNeighboursDR5

Cross-neighbours between SSA Source objects and the SDSS DR5.

All SDSS DR5 objects within 10 arcsec of each SSA Source object are
recorded in the cross-neighbours table. This table can be used, for
example, to get SDSS counterparts to an SSA object with a defined
positional tolerance (up to the maximum angular radius of 10 arcsec).
The BestDR5..PhotoPrimary view and SSA.Source table were joined to
generate the cross-neighbours.
