• The Anderson orthogonality exponents K_+ for introducing a localized perturbation into an electron gas and K(a) for displacing the localized potential by a vector a are discussed for one- and two-dimensional systems. It is shown that the "smoothness" of the potential enters very differently in the exponents K_2 and K(a). The controversial point of the boundedness of the two exponents is clarified.
