Outflow mass-loss rate Ṁ_out (left), kinetic power ratio (centre) and momentum rate ratio (Ṁ_outv) / (L_AGN/c) (right) as a function of the projected distance from the quasar position. These plots have been obtained by dividing the outflowing clumps (see Sect. 3.4) in bins of ΔR = 0.6 arcsec, corresponding to ≃3 kpc. The plots show, in correspondence of the average R of each bin, the total Ṁ_out, and (Ṁ_outv) / (L_AGN/c) obtained by adding up the contribution of all the outflowing clumps within the bin. For an explanation of the error bars, see caption of Fig. 7.
