Set of maps of the u0τ parameter plane for the case of η = 500 (top), and of the ητ plane for u0 = 10, showing allowed and excluded domains for the dipole reversal time (left) and ratio of dipole moment at cycle minimum to the maximal dipole moment (right). Units are m s−1 for u0, km2 s−1 for η and years for τ.
