Marker 3: (a) Time differences between the extrema of x(t) and y(t); (b) Time difference versus time diagram with its zero value t1; (c) Comparison of the transformed experimental results (magenta solid line) and the fitted numerical results (black dots) along the X-axis; (d) Comparison of the transformed experimental results (magenta solid line) and the fitted numerical results (black dots) along the Y-axis; (e) Comparisons for the trajectories.
