Spectral behavior of the total intensity, for some choices of parameters. Upper panel: Spectra of ℐ, for a fixed choice of s (=2) and β (=1), and different choices of the level of the random MF, here isotropic and characterized by the standard deviation σ. ℐ is normalized by taking $A=H=K=x_{\mathrm{cut}}=\overline{B}=1$ in Eqs. (11) and (18). The dashed line represents the case without random MF, while the other colored lines refer to values of ${log}_{10}(\sigma /\overline{B})$ ranging between −0.5 and +1.5, in steps of 0.5. Lower panel: Same as above, but scaled with the pure power-law solution from Paper I.
