Mass outflow rate distribution of the ionised gas derived from [NII]λ6584 for NGC 4945 and from [OIII]λ5007 for Circinus and NGC 7582. Left panels: 2D maps of the mass-outflow rate distribution. Right panels: radial profile of the mass-outflow rate from the cone vertex. The volume average mass-outflow rate obtained with the MOKA^3D-based method (dashed green line) is compared to the standard method result (dotted blue line). The standard method estimate of the volume-average Ṁ_out is underestimated by a factor of two in NGC 4945 and Circinus. From top to bottom: NGC 4945, Circinus, and NGC 7582.
