Radial profile of the ionised mass outflow rate ${\dot{M}}_{\mathrm{out}}^{\mathrm{ion}}$ as a function of the average projected distance from the AGN. Solid and dashed lines are estimates of ${\dot{M}}_{\mathrm{out}}^{\mathrm{ion}}$ by using the average and the maximum $v_{\mathrm{out}}^{\mathrm{ion}}$ at every radius. The blue dashed line is the integrated mass outflow rate, 0.076 ± 0.017 M_⊙ yr⁻¹, with the blue shading representing its uncertainty.
