    • In general, however, calculation of observables that are affected by propagation effects requires taking into account the contributions of (at least) two trajectories.

    • Strictly speaking, the slopes of the phase dependence are slowly varying functions of Up. The derivative of the phase with respect to Up is about -3.3 for small Up and increases slowly as Up tends to the plateau cutoff threshold. Above this threshold, this derivative very rapidly attains values of the order of -5.7 and -5.8 and then decreases very slowly toward an asymptotic value of -2π at Up to∞.

    • This is done by multiplying the contribution of the saddle point τ1 by a factor that is 1 above the cutoff and becomes gradually smaller in the small range of intensities close to the plateau cutoff transition.
