Sdss DR13 Join (gaiadr3.sdssdr13_join)
The table has 468180883 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
original_ext_source_id) to the corresponding additional numerical identifier (
clean_sdssdr13_oid are present in the cross-match output tables (
sdssdr13_neighbourhood). However, in case there are suspected duplicates in the external catalogue, different
original_ext_source_id will correspond to the same
clean_sdssdr13_oid. In the cross-match output table only the
original_ext_source_id of the source with the best astrometry among the suspected duplicates will be listed. In practice, users may use the
original_ext_source_id 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
clean_sdssdr13_oid 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.
