\caption{Maximum variability time scales $\tau_{\rm max}$ of the 1300--1350 \AA\ light curves, corrected for time dilatation. The third column shows 
the values of $\tau_{\rm max}$ obtained with $B=0$, i.e. the SFs have been
fitted without a slow variability component. The last column presents the corresponding range of event durations $2\mu_{1300}$, deduced from the simulations. }
