Figure 8

The present figure shows the evolution ofunder the Poincaré map Φ for time intervals of different lengths. The parameters used are $k=1$, ${\mu }_1=2$, ${\mu }_0=1/2$, as before, while for $t_{+}-t_{-}$, we have considered the cases 35, 60, 100, 150 (from the left to the right). For graphical reasons, a slightly different x- and y-scaling has been used.
