Rave DR6 Neighbourhood (gaiadr3.ravedr6_neighbourhood)

The table has 456370 rows, 6 columns.

Description

Table Ravedr6Neighbourhood includes all good neighbours for each matched RAVE DR6 object. A good neighbour for a given RAVE DR6 source is a nearby Gaia object whose position is compatible (within position errors) with the RAVE DR6 target. The cross-match algorithm is not symmetric and searches RAVE DR6 sources counterparts in Gaia. The cross-match algorithm is positional and exploits the full~5 parameter covariance matrix of the Gaia astrometric solution when available and the external catalogue positions and position errors. In addition it takes into account the Gaia environment using the local density.Please note that the cross-match algorithm is a trade-off between multiple requirements, in particular between completeness and correctness. It is thus not limited to a simple cone search.Reference papers DR1-DPACP-17 DR2-DPACP-41
