Caption: Figure 1.
Flux-calibrated, Galactic-extinction-corrected, mean spectra of the 17 quasars reported in this work. The spectra have been shifted in the y-axis for display purposes, starting with a zero shift for CT252, five units of flux for J002830, 10 units of flux for CT250, and so on. The gray lines approximately demarcate the wavelength region corresponding to the R-band filter.
