  1. The center of integration is set at the adatom, with a horizontal radius of 0.53 \(\mathring{\textrm{A}}\) in the plane, a quarter of the horizontal distance to the nearest atom of the adatom, to extract the component of directly above the adatom. The labels for adatoms correspond to those in Fig. 4.
