MBH mass–stellar mass relation for the sources in our sample. We show the local AGN from Reines & Volonteri (2015) as blue stars and orange diamonds, with the underlying shaded area correspond to the 1σ and 2σ uncertainties around the best fits to the local samples (grey and cyan for inactive and active galaxies, respectively). The original data from the literature are shown as green circles, whereas our new estimates are reported as red dots (left panel) and purple crosses (right panel) for the two virial factors considered. For completeness, we also show as the dotted magenta lines constant mass ratios of 0.01 and 0.1.
