(a) Real part of the eigenvalue of the fixed point along the path as a function of the linear growth rate and phase velocity of the base uniform flow in the full model, for the same system as in Figure 2(b). (b) Imaginary part of the eigenvalue of the fixed point along the path as a function of the wavenumber with phase velocity c for the base uniform flow in the full model, for the same system as in Figure 2(b).
