Notes. Columns 2 and 3 respectively list the large-scale and small-scale fields, once quadratically averaged over the reconstructed maps. Column 4 gives the time-averaged small-scale field integrated over the visible hemisphere 〈 Bs〉. Columns 5 to 7 respectively list the polar strengths of the dipole component Bd, the tilt of the dipole component to the rotation axis and the phase towards which it is tilted, and the amount of magnetic energy reconstructed in the poloidal component of the field and in the axisymmetric modes of this component. Error bars on field values and percentages are equal to ≃10%, whereas dipole tilts are accurate to ≃5°.
