Fig. 3
a Number of peaks, N (as defined in Fig. 2c), of the trajectories for various initial positions (\({\hat{x}}_{0},{\hat{z}}_{0}\)). Note that both axes have different scales to improve the visibility of the symbols. b Peak amplitudes, A, of trajectories as defined in Fig. 2c for \({\hat{x}}_{0}=0.0033\). Amplitudes are decreasing for later peaks; the same trend has also been found for other values of \({\hat{x}}_{0}\) (data not shown). c Amplitudes of the first peak, A1, for all investigated initial positions, as long as the peak exists. d, e Normalised inter-peak distance, \(\hat{L}\), of trajectories as defined in Fig. 2c for all investigated \({\hat{z}}_{0}\) for d \({\hat{x}}_{0}=0.0033\) and e \({\hat{x}}_{0}=0.01\). f Normalised inter-peak distance between the first and second peak, \({\hat{L}}_{2}\), for \({\hat{x}}_{0}=0.0033\) and 0.01. Lines are guides for the eyes
