Mean rest-frame SEDs for low-z quasars (top) and high-z quasars (bottom). The top and bottom panels depict the mean rest-frame SEDs for low-z and high-z quasars, respectively. The black and green shaded regions highlight the areas utilized for computing L_IR and L_agn, respectively, in the all-points method. Each photometric observation is labeled with the filter name. The error bars denote the 1st and 3rd quartiles.
