TABLE  CrossNeighboursEDR

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

All SDSS 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 SkyServer.PhotoPrimary and
SSA.Source tables were joined to generate the cross-neighbours.
