The authors decompose the lowest-order nonlocal corrections to the local-density approximation to the exchange and correlation component of the metallic surface energy in terms its wave-vector components. Comparison with the full exchange shows significant improvement over the local-density form. An interpolation between the surface-plasmon-dominated small-wave-vector contributions and the nonlocal correction for large q is suggested, and some of the difficulties inherent in this method are discussed
