Choice of the exponent n. Calculated HAADF intensity ratios between the three inner standards, taken two by two, for n = 1.7 (black dash and dot line, dark lozenges) and n = 2 (blue solid line, blue circles) as compared to the relevant experimental ratios (red solid line, red squares). Within experimental errors, exponent n = 2 fits very well to the experiment.
