Distribution of the BP flux (left) and RP flux (right) as sampled by SMS-gen (Creevey et al. 2023) of 42 944 quasars published in Gaia DR3 that have spectroscopically confirmed redshifts in the Milliquas 7.2 quasar catalogue of (Flesch 2021; type = Q). Dotted lines show the dominant quasar emission lines. Spectra are individually normalized in order to have a maximum flux of 1.0 and are then averaged in redshift bins of 0.01, with the inverse variance of the sampled fluxes used as the weight during the computation of the mean.
