RAVE DR5 Join

Convenience table to be used to join RAVE DR5 catalogue with the cross-match results. The table links the external catalogue original sourceId (originalExtSourceId) to the corresponding additional numerical identifier (cleanRavedr5Oid).Both originalExtSourceId and cleanRavedr5Oid are present in the cross-match output tables (Ravedr5BestNeighbour and Ravedr5Neighbourhood).However, in case there are suspected duplicates in the external catalogue, different originalExtSourceId will correspond to the same cleanRavedr5Oid. In the cross-match output table only the originalExtSourceId of the source with the best astrometry among the suspected duplicates will be listed.In practice, users may use the originalExtSourceId in the original catalogue to find the matching source with the best astrometry. Users interested to find all matching suspected duplicates should instead use the cleanRavedr5Oid in the join with the cross-match result tables.See Chapter [chap:crossmatch], for more details on the duplicates in the external catalogues and their treatment in the cross-match computations.
