Two-parameter bifurcation diagram of the fast system of Equations 9a-9c in the (u, r x )-plane. This includes loci of saddle-nodes of fixed points SNf, Hopf bifurcations H, saddle-nodes of periodic orbits SNp, and homoclinic bifurcations HC. There are three labeled codimension-2 bifurcations: a Bogdanov-Takens bifurcation BT at (u, r x )(3.325,3.029), a Bautin bifurcation B at (u, r x )(0.4945,4.740), and a SNpHC at (u, r x )(1.364,5.203). Plotting conventions follow Figure 6.
