Distribution of the Hubble diagram residuals (middle panel of Fig. 9) as a function of redshift for the quasars with a broad (FWHM > 2000 km s−1) component of the Mg II emission line in the clean sample. The black and red points represent the mean and median of the residuals in narrow redshift intervals, respectively. Symbol keys as in Fig. 1.
