(color online) (a) Variation of the amplitude ψ_m for DL structures against q for different values of μ_n. Here, the Sagdeev result is denoted by a solid line and the analytical expression is denoted by a doted line. (b) Variation of the real Mach number M/M_C for DL structures against q for different values of μ_n. Other parameters are the same as in Fig. 2.
