\(W_{s,4}(\phi )\) for \(H=0.32, 0.36\) and 0.4 (from left to right, respectively). The area enclosed by \(W_{s,4}(\phi )\) is colored in blue. The two infinite tongues colored in light and dark blue are the result of the backward integration of the tongues colored in the same shade of blue in Fig. 3.
