Evolution of the pseudo product P_r Q_r + P_i Q_i as a function of k_p in the LF mode with the parameters of Fig. 4. It appears that P_r Q_r + P_i Q_i changes its sign for particular values of the wave number. These critical wave numbers are k₁ = 0.01533 rad⋅cell⁻¹, k₂ = 0.08072 rad⋅cell⁻¹, k₃ = 0.99 rad⋅cell⁻¹, and k₄ = 1.025 rad⋅cell⁻¹.
