Variation of the width versus the velocity V for two different values of \(\beta\). The blue curve corresponds to \(\beta =0.066\) (as in Fig. 12) and the red curve corresponds to \(\beta =0.0644\) (cf. Fig. 8). The remaining parameter values are: \(\zeta =0.0001\), \(\delta =0.01\), \(\mu =16\) and \(Q=1\).
