Fit of the source PG 0844+349. For this source, adding a galaxy template to the blue line fit or a prominent Balmer continuum does not lead to a satisfactory fit. Instead, assuming an intrinsic reddening of the source (corrected by assuming E[B − V] = 0.1 mag), the new fit (red line) describes the AGN continuum for Log ν >  14.8 (for smaller frequencies, we added the host-galaxy emission). Right panel: thick lines corresponds to the first fit (blue line on the left panel); dashed lines to the second one (red line on the left panel).
