We have measured and calculated the intensity profiles for S 2[ital p] photoemission at 1327 eV from the well-defined adsorbate system, [ital c](2[times]2)S on Ni(001), and have analyzed these via several holographic imaging procedures. Images of nearest-neighbor S atoms are clearly seen in both experiment and theory, and their positions are improved if effects due to twin images are suppressed by analyzing only a half hologram. Image positions are further improved to within [plus minus]0.2--0.3 A with corrections for scattered-wave amplitudes and phase shifts.
