\caption{\label{fluxes}Total magnetic fluxes $\Phi_{\rm PC}$ at the polar areas of the Sun around the minimum of the sunspot cycle. The three numbers for the entries from this work refer to the fluxes with magnetic filling factor $\alpha$~=~0.1, $\alpha$~=~0.3, and $\alpha$~=~1.0, from left to right. The signs indicate the polarity.}
