Fig. 3.
Normalized histogram of the bias △z = zphot − zspec between photometric and spectroscopic redshifts for different samples. The phometric redshifts are obtained using the NW kernel regression. Around 76% of the spectroscopic quasars in the Boötes field have photometric redshifts that are correct within |△z| = 0.3 (see Table 3).
