Ratio of RMS horizontal and RMS vertical magnetic field components (left panel), RMS vertical magnetic field component (middle), and modulus of the magnetic field (right) for the three stellar SSD simulations (G2V in yellow solid line, K0V in orange dashed, and M2V in brown dot-dashed) averaged over time and surfaces of constant number of pressure scale heights N_p (see Eq. (11)). The three top axes show the geometrical height for the three stars.
