Left: Schematic overview of the parametrization of NCi as a function of Tn when T0=Tmin and Tfinal=Tmax. The resulting function NCi(Tn) is single-valued (SV) for all Tn [0,1]. Right: Schematic overview of the parametrization of NCi as a function of Tn when T0=Tmin and Tfinal<Tmax. The resulting function NCi(Tn) is single-valued (SV) for Tn [0,Tn,f[ and multi-valued (MV) for [Tn,f,1]. In both figures, the arrows indicate the direction of increasing time. 2/2
