10.17876/gaia/edr.3/38RAVE DR5 NeighbourhoodEuropean Space Agency (ESA)DPAC ConsortiumAstronomyLeibniz Institute for Astrophysics Potsdam (AIP)Table ravedr5_neighbourhood includes all good neighbours for each matched RAVE DR5 object. A good neighbour for a given RAVE DR5 source is a nearby Gaia object whose position is compatible (within position errors) with the RAVE DR5 target. The cross-match algorithm is not symmetric and searches RAVE DR5 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.
