Relation between Ṁ_Hion and L_bol. Turquoise points are our ionized mass outflow rates (Ṁ_Hion), calculated from either Paα or Brγ and using TR-based electron densities. Data of other QSO2s are shown with different colors and symbols. Open squares are mass outflow rates from Fiore et al. (2017), divided by 130 (see text). The dashed and dotted gray lines are the scaling relations from Fiore et al. (2017) and Davies et al. (2020), respectively, and the solid black line is the linear fit to all the data points included in the plot. The orange shaded area represents the 1σ confidence interval of the fit.
