Sdss DR13 Join (gaiaedr3.sdssdr13_join)
The table has 468180992 rows, 2 columns.
Convenience table to be used to join SDSS DR13 catalogue with the cross-match results. The table links the external catalogue original sourceId (originalExtSourceId) to the corresponding the additional numerical identifier (sdssdr13Oid). Both originalExtSourceId and sdssdr13Oid are present in the cross-match output tables (sdssdr13BestNeighbour and sdssdr13Neighbourhood). However, in case there are suspected duplicates in the external catalogue, different originalExtSourceId will correspond to the same sdssdr13Oid.
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 sdssdr13Oid in the join with the cross-match result tables.
See Documentation, Chapter 8, for more details on the duplicates in the external catalogues and their treatment in the cross-match computations.
