(a) Diffraction pattern of the Ag(001) substrate covered by 1 ML of BDA arranged in a four-domain structure. The pattern consists of four intense substrate spots around the edges and many Moiré spots originating from the long-range order superlattice periodicities. (b) Single domain diffraction pattern measured on an individual superlattice domain. (c) Real and (d) reciprocal models of Moiré periodicity. The diffraction pattern consists of two rotational and two mirror domains. (e) Illustration of the sensitivity of diffraction spot positions to small changes in superlattice models. Diffraction model 1 matches the experimental data, whereas slight changes in models 2 and 3 lead to apparent changes in spot positions that can be used for precise modeling.
