Redshift distribution histogram for the 121 461 new quasars in the LQAC4 for which DSS images and the morphological indexes were searched for and calculated. The percentage counts are obtained in 0.01 redshift bins. All redshift are spectroscopic. There are clearly two concentrations, inherited from the SDSS Main and BOSS populations.
