As in Fig. 4. The solid black thick line is δ(ϵ1 = 0.1 Mm-1, ϵ2 = 0.01 Mm-2), whereas the solid black thin line is δ(ϵ1 = 0.1 Mm-1, ϵ2 = −0.01 Mm-2), both for the fundamental mode. The dashed lines are similar but for the first overtone. The remaining parameters are L = 100 Mm, l = 5 Mm, csc = 200 km s-1, and χ = 100, as in Fig. 3.
