Continuation in ε of the twins \(\xi '_{1}\)–\(\xi '_{16}\) of canard orbits \(\xi _{1}\)–\(\xi _{16}\), for system (32) with \(I=9.74\). Panel (a) shows the \(L_{2}\)-norm of the canard orbits versus ε. Panels (b)–(e) show the canard orbit \(\xi '_{6}\) for \(\varepsilon =0.0083\), \(\varepsilon =0.003\), \(\varepsilon =3.0 \times 10^{-5}\) and \(\varepsilon = 2.39441 \times 10^{-8}\), respectively
