Histogram of the observed r-band magnitudes of the dusty QSO-DLAs compared to the SDSS-DR12 QSO-DLAs and the total number of quasars from the SDSS-DR12Q survey at redshifts 1.5–4.0. The mean r-band magnitude of 18.78 mag for the dusty QSO-DLAs is roughly two magnitudes brighter than the mean of r = 20.39 mag and r = 20.65 mag for the full sample of SDSS-DR12 QSO-DLAs and quasars, respectively, in the same redshift range.
