| A concordance of all the objects from Spectro, Best, or Target that "smell" like a QSO NOTE: This is a derived science table that may not be loaded for every data release. It is scheduled to be reloaded for DR5. |
| QsoConcordance is built from QSOCatalogAll. For each entry in QSOCatalogAll, QsoConcordance collects popular fields from the three different databases involved (Spectro, Best, Target). Its fields are itemized and documented below. See also the QsoCatalogAll table description. |
