Histograms of MBH for star-forming (blue), composite (magenta), Seyfert (green), and LINER (red) galaxies in our sample as classified by the BPT diagram. The error bars are the Poisson fluctuations of the number in each bin. Note that we have put all broad-line sources into the “Seyfert” subset, whatever their BPT types are.
