Q–Q (, see text in Sect. 3.1) plots for the final calibrated consensus redshift predictions for the galaxy population (left panel) and the optical/infrared and X-ray selected AGN population (right panel). Coloured lines represent the distributions in bins of apparent optical magnitude while the thick black line corresponds to the complete spectroscopic training sample. Lines that fall above the 1:1 relation illustrate under-confidence in the photo-z uncertainties (uncertainties overestimated) while lines under illustrate over-confidence (uncertainties underestimated).
