32. We favor the dressed modified MSFA in length gauge in accordance with the results of W. Becker, J. Chen, S. G. Chen, and D. B. Miloević, Phys. Rev. A PLRAAN 1050-2947 10.1103/PhysRevA.76.033403 76, 033403 (2007). Numerical comparison of different versions of the MSFA for the direct ATI was presented in Ref.. We have checked that the numerical results for all versions of the rescattering molecular ATI qualitatively agree.
33. Actually, when in the figures we label some partial T -matrix contribution with, say, T++ - we do not plot this amplitude but rather its square T++ - 2. This should not lead to confusion.

36. For θL =90°, the two-center interference perpendicular to the molecular axis (θ=90°) is always constructive for N2 by symmetry, so that there cannot be any interference minima. In contrast, for θL =0° destructive interference does occur for θ=0°. However, for the parameters of Fig. 6, the m=0 destructive interference is at very low energy and the next (m=1) destructive interference is already at an energy far outside the figure.
37. The origin of these "canyons," which are comparatively steep and narrow, is essentially the same as in atoms and has little to do with the presence of two centers. They are caused by destructive interference of the molecular analogs of "the long" and "the short" orbit as well as "longer" orbits. A quantitative understanding would require developing the molecular extension of quantum-orbit theory.
