Comparison of the outflow properties with the bolometric luminosity of the AGN (L_bol) and the Eddington ratio (L_bol/L_edd). Left panel: total kinetic energy of the outflow vs. L_bol. These quantities show a linear dependence. Right panel: velocity of the outflow vs. L_bol/L_edd. Most sources show velocities between ∼200 and ∼800 km s⁻¹ with no clear trend with L_bol/L_edd or differences between the various spectroscopic classes. The open symbols correspond to sources without detected extended outflow.
