\caption{Frequencies $\nu$, periods $\nu^{-1}$, maximum power~$P_{\rm max}$, significance levels~$p$, and latitudes~$\vartheta$ (where the power exceeds the given significance level) for the labeled regions in Figs.~\ref{fig8}a--\ref{fig8}d (cycle~21). The columns on the left give the values for the net magnetic flux, the columns on the right the values for the total magnetic flux. The error $\Delta \nu=1.5~{\rm nHz}$ is half the frequency resolution. The time intervals were determined using the $99.0\%$~significance contours of Morlet wavelets with nondimensional frequency~18 (cf.~Sect.~\ref{subsec2.2}). }\label{tab4}
