Three computed submanifolds of \(S^{s}_{\varepsilon }\) of system (11) with \(\mu =9.2\) and \(\varepsilon =0.01\). The left column illustrates the three submanifolds, projected onto the (\(x,y,z\))-space, together with the corresponding boundary conditions \(\widetilde{\varSigma }_{0}\) and \(\widetilde{\varSigma }_{1}\) (light- and dark-blue sections). The right column shows the three submanifolds, projected onto the (\(x,z\))-plane and the (\(w,z\))-plane, where we also include stable (blue) and unstable (red) eigenvector directions at a selection of points on \(S^{s}\)
