A treasure hunt in the pool of spectra classified as high-redshift QSOs by the spectroscopic pipeline of the SDSS DR16

Open Access

Fig. B.1.

MBSEDs (in the observer’s frame) for the ten QSOs with the highest colour excess E(g − z). The flux is in units of erg s⁻¹ cm⁻² Å⁻¹. The black squares with error bars are the fluxes from photometric data; the SDSS spectra are plotted in green (both corrected for Galactic foreground extinction). The template spectrum for bright QSOs of type 1 from Polletta et al. (2007) is shown in blue.
