Figure 4

Top panel: finite fast pulse trains computed from the initial perturbation (3) with Δ = 0.1 for different values of A and R when av = 0.5. The integers correspond to the number N of pulses in the wave train, the bold italic fonts corresponding to the solutions described in fig. 3. Bottom panel: variation in N in the vicinity of the extinction boundary, in the region indicated by the small rectangle in the top panel. The numerical integration of eqs. (1) was performed with Δx = 0.005 and Neumann boundary conditions on an L = 50 domain.
