We apply the technique to AgPd alloys in conjunction with the tight-binding linearized muffin tin orbitals basis. We also indicate why the same technique is ideal for application to the more accurate screened-KKR and allows us to go beyond the single site coherent potential approximation and include multi site effects like short-ranged ordering and local lattice distortions due to size mismatch of the constituent atoms.
