Various quantities detemined in this work, shown as function of galactocentric radius r as projected onto the major axis: synchrotron halo scale height h_syn at 1.5 and 6 GHz, halo magnetic field scale height h_B2, mid-plane total magnetic field strength B₀, advection speed V₀, CRE escape height h_esc, and diffusion coefficient D₀. For NGC 891, h_B2 and V₀ are shown for constant (a) and (including h_esc) for accelerated CRE advection (b). For NGC 4565, h_B2 and D₀ are shown for energy-dependent (c) and energy-independent CRE diffusion (d). In case of V₀, D₀, h_B2, and h_esc, the average between the northern and southern values is plotted. Negative values of r are east and positive ones are west of the minor axis.
