G_BP − G_RP, vs redshift for the subsets classlabel_dsc (top) and classlabel_dsc_joint (bottom) of the SDSS-DR14Q-Gaia DR3 cross-match. The orange points are classlabel_dsc = galaxy (top) and classlabel_dsc_joint = galaxy (bottom). Middle panel: quasars with classprob_dsc_combmod > 0.5 for any of the three stellar classes used in DSC-Combmod. The red curves show the median G_BP − G_RP, and the 16% and 84% quantiles for all sources in the cross-match, regardless of the DSC class (so are the same in all panels).
