(Color online) Contour plot of the trajectories \(\dot {R}(\theta)\) for two different sets of relaxation parameters. The red line is the line for which \(\dot {R}=0\). The blue and green lines are the set of points where \(\dot {r}\) is minimum, while the points of the yellow one correspond to a maximum. The small inserts display in the (y,z)- plane the trace of the corresponding sets of points. Circles of different radii are also plotted to help the reading
