RAVE DR6 Join

The table links the external catalogue original sourceId (<tt>originalExtSourceId</tt>) to the corresponding additional numerical identifier (<tt>ravedr6Oid</tt>).Both <tt>originalExtSourceId</tt> and <tt>ravedr6Oid</tt> are present in the cross-match output tables (<tt>Ravedr6BestNeighbour</tt> and <tt>Ravedr6Neighbourhood</tt>).However, in case there are suspected duplicates in the external catalogue, different <tt>originalExtSourceId</tt> will correspond to the same <tt>ravedr6Oid</tt>.

In the cross-match output table only the <tt>originalExtSourceId</tt> of the source with the best astrometry among the suspected duplicates will be listed.In practice, users may use the <tt>originalExtSourceId</tt> 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 <tt>ravedr6Oid</tt> in the join with the cross-match result tables.See Chapter <a href=#>chap:crossmatch</a>, for more details on the duplicates in the external catalogues and their treatment in the cross-match computations.</p>
