Comparisons of BH masses derived by different methods for the same object. Left-hand panel shows the comparison between the BH masses as given in S11 (Shen et al. 2011) and those calculated for the same object in DR12Q (Pâris et al. 2017) using equation (1). Right-hand panel shows the comparison between the BH masses calculated for an object in DR12Q using equation (1) and (2). The solid lines represent linear expressions fitted to the data points.
