The dynamical trajectories using values given in Table 1. In (a) the initial conditions supplied are $G=\left({\overline{s}}_1^{-},{\overline{e}}_1^{-},0.999\times {\overline{y}}_1^{-},{\overline{z}}_1^{-}\right)$; and in (b), $G=\left({\overline{s}}_1^{-},{\overline{e}}_1^{-},1.001\times {\overline{y}}_1^{-},{\overline{z}}_1^{-}\right)$. In the former case, the initial conditions are contained in the region of attraction of P⁰, while in the latter, P⁺. Here we have q = 1, γ < γ ₊ , p > p ₀ and β >β ₀ .
