29. The overlap integrals between the inner-shell orbitals of the neutral molecule and that of the molecular ion are found to be approximately 1, and are therefore dropped here for the sake of simplicity.
30. Inclusion of the Coulomb correction factor to the KFR-rate formula, estimated from a WKB approximation (cf. [19]) has been shown to reproduce the absolute values of the total ionization rates as a function of the field intensity for a whole set of atoms [19], and is adopted here mutatis mutandis to the molecular case.

37. We also find a similar suppressed ionization for circular polarization that is observed in the corresponding experiment [7] as well.
