Galactic sky distribution of the fraction of DSC sources classified as quasars (left) and galaxies (right) according to Specmod (top), Allosmod (second), Combmod (third), and Specmod and Allosmod (bottom) probabilities being greater than 0.5 for that class. Bottom two rows are identical to classlabel_dsc and classlabel_dsc_joint (respectively) being set to the appropriate class (see Sect. 3.2.4). The plot is shown at HEALPix level 7 (0.210 deg²) with each cell showing the ratio of the sources classified to the total number of sources with DSC results (1.59 billion over the whole sky). The logarithmic colour scale covers the full range for each panel, and is therefore different for each panel.
