Table 7.
SDSS spectral classes for objects in the galaxy_candidates table.
| SDSS | galaxy_ | classlabel_ | classlabel_ | Vari- | OA | UGC | Surface | |
|---|---|---|---|---|---|---|---|---|
| candidates | dsc | dsc_joint | classification | brightness | ||||
| TOTAL | 534 154 | 477 939 | 48 460 | 360 217 | 105 296 | 248 196 | 96 918 | # |
| GALAXY | 98.0 | 97.9 | 95.1 | 99.7 | 95.6 | 97.9 | 99.7 | % |
| QSO | 1.6 | 1.7 | 4.9 | 0.3 | 3.9 | 2.0 | 0.3 | % |

Notes. The first row gives the number of sources found in SDSS for the whole table (first column) and for each module (subsequent columns). The following rows give the percentage of sources of each SDSS class among these. The GALAXY row can be thought of as a measure of the purity against sources with SDSS spectral classifications, which by design is dominated by extragalactic sources, so is an overestimate of the purity of a sample selected at random from Gaia.
