Target phase space for the two-faceted cup divided into 100 bins. Five different paths are found. The rays with coordinates \((q^{\mathrm{min}}, p)\) and \((q^{\mathrm{max}}, p)\) in \(T_{4}\) that are located at the boundaries \(\partial R(\Pi )\) are depicted with dots, the color of the dots depends on the path Π followed by the rays. Using the ray mapping method, only these rays need to be traced from S to T for the intensity computation
