Two-parameter bifurcation structure for the desingularized system. The curves TR1 and TR2 represent the transcritical bifurcations (type II folded saddle-nodes). The curves SN1-SN4 represent saddle-node bifurcations (type I folded saddle-nodes). The horizontal line is where the fold curves L+ and L- coalesce. A codimension-2 bifurcation occurs at the intersection of the SN curves.
