In paper [1] (Avotina et al. Phys. Rev. B,74, 085411 (2006)) the effect ofFermi surface anisotropy to the conductance of a tunnel point contact, in thevicinity of which a single point-like defect is situated, has been investigatedtheoretically. The oscillatory dependence of the conductance on the distancebetween the contact and the defect has been found for a general Fermi surfacegeometry. In this paper we apply the method developed in [1] to the calculationof the conductance of noble metal contacts. An original algorithm, whichenables the computation of the conductance for any parametrically given Fermisurface, is proposed. On this basis a pattern of the conductance oscillations,which can be observed by the method of scanning tunneling microscopy, isobtained for different orientations of the surface for the noble metals.
