Top panel: time-averaged parity of individual cycles (full line) and instant values of the parity of Eq. (14) at the cycles’ maxima (dotted) as the functions of computed cycle number. The data points for individual cycles are connected by straight lines for better visibility. Bottom panel: asymmetry measure (Eq. (12)) of the toroidal field for the cycles’ maxima (full line) and the asymmetry (Eq. (13)) of the polar fields at the cycles’ beginnings (dotted). The straight horizontal line indicates the range, for which the next two plots show the detailed time dependencies.
