Number of entries in our quasar catalogues as a function of classification confidence. The orange and green lines include the high-z and low-z entries, respectively. The blue lines are the sum of the orange and green lines. Solid lines include all the entries, irrespective of their magnitude, whilst the dashed lines exclude objects fainter than r = 23. Horizontal grey bands indicate the expected number of quasars down to magnitude r = 23 according to the models from Palanque-Delabrouille et al. (2016). The left panel shows the number of objects for the point-like catalogue, and the right panel also includes the extended sources. We note that in the bottom panel, the number of objects including all magnitudes is unreasonably large, and thus we choose to focus the y label on the magnitude-limited lines.
