    • Both the imaginary parts are positive: As a rule, any saddle that has a negative imaginary part of the action cannot be visited by the steepest-descent contour. This is so because in the original integration the action was real (Formula presented) and the deformation procedure does not lead to an increase of (Formula presented) by construction

    • Even though the amplitude (2) contains both rescattered and direct electrons, in the context of the saddle-point and the uniform approximation, it is preferable to calculate the direct electrons from amplitude (1) and then, to avoid double counting their contribution, to disregard very short quantum orbits (Formula presented) in the amplitude (2); cf.

    • For elliptical polarization, the energy range where direct and rescattered electrons interfere is larger, owing to the faster drop of the rescattered electrons for increasing energy. Indeed, interference between direct and rescattered electrons has been observed in this case both in the experiment and in theory; see G. G. Paulus, F. Grasbon, A. Dreischuh, H. Walther, R. Kopold, and W. Becker, Phys. Rev. Lett. 84, 3791 (2000).
