9. The term "modified" is introduced to distinguish our molecular strong-field approximation theory from the standard MSFAs [4,5]. Our modified MSFA includes an additional term and enables laser-field dressing of the initial states. In [8], we have introduced four versions of the modified MSFA, while in the present work we show that the so-called dML version is superior to the standard MSFAs and to the other three versions of the modified MSFA. The term "improved" has the same meaning as for the improved SFA for atoms; that is, inclusion of an additional interaction of the ionized electron with the parent (atomic or molecular) ion via its rescattering off this core.

17. The absence of this suppression was an argument that the velocity-gauge MSFA is superior to the length-gauge MSFA. We show here that this argument cannot be used for our dressed modified length-gauge MSFA, since it leads to the correct suppression factor, Eq. (1).
