Comparison between dynamical virial mass (M_vir) computed using flux map properties and dynamical mass (M_dyn) obtained with the full kinematical model of the gas velocity field. The dashed line indicates the 1:1 relation, while dotted lines are 1 dex shifts. The objects represented with star symbols are upper limits on virial mass, since their emission appears consistent with a point-like source (as a result of 2D Gaussian fits within CASA). In these cases, following Willott et al. (2015a), we assume β = 55 deg as disc inclination angle. The black square indicates PSO J183−05, for which we retrieved a lower limit on M_dyn, but for which M_BH is not available.
