Comparison between SE mass estimates and reverberation measurements. Upper: SE Hα-based virial product predictions using Eqs. (14) and (15) in panels (a) and (b), respectively. The coefficients for the best fit appear in the first two lines of Table 1. Blue circles are data from Table A.1, and green triangles are from Table B.1. The solid line is the best fit to the data, and the dotted red line shows where the measures are equal. The short- and long-dashed lines show the ±1σ and ±2.6σ envelopes, respectively. Lower: Corrected SE masses from Hα-based virial product predictions using Eq. (17) (panel c) and Eq. (19) (panel d), in both cases with log f = 0 arbitrarily.
