Caption: Fig. 8.
BH masses measured from all of the spectral data (HST and ground‐based) compared to those measured from using the ground‐based spectral data only. The confidence bands are 68% uncertainties. All measurements based on ground‐based data alone are consistent with measurements based on HST plus ground‐based data. The masses from the ground‐based spectral data may tend to slightly underestimate those obtained including the HST spectral data.
