From a sample of 570 QSOs with redshifts ranging from 0.2 to more than 3, the optically most luminous are selected, and a plot of absolute magnitude versus redshift is obtained, the absolute magnitudes being calculated on the assumption that the QSOs are at the cosmological distances implied by their redshifts. This plot shows that for a redshift in excess of unity, absolute magnitudes of the brightest QSOs remain nearly constant. The (log z-apparent magnitude) plot for the brightest QSOs is also obtained. The slope of the least-squares-fit line is consistent with the expected value of 0.2.
