Log(R_1/2) and log(L₃₀₀₀) vs. log(M_BH) (upper and middle panels, respectively). Black and red circles in the top panel show R_1/2 assuming an inclination angle of 30° and 60°, respectively. Red points in the middle plot show data after correcting for intrinsic absorption as well. A plot of log(L₃₀₀₀) vs. logarithm of half half-light radius is shown in the bottom panel. Solid lines show the best fit to the data, while dashed lines show the 1σ confidence regions (see text for details).
