Cross-neighbours between u07b20 and 2MASS point sources. |
All 2MASS point sources within 10. arcsec of each source from u07b20 data are recorded in this cross-neighbour table. The table u07b20Source was joined to the twomass_psc table to create these cross-neighbours. Use this table for any cross-querying of u07b20 data with point sources from 2MASS. |
