| Cross-neighbours between the Gaia DR2 source table and 2MASS point sources |
| All TWOMASS..twomass_psc sources within 5 arcseconds of each source from the Gaia DR2 source table are recorded in this cross-neighbour table. The table gaia_source was joined to the twomass_psc table to create these cross-neighbours. |
