The method allows a detailed characterization of patterned substrates grown by epitaxial lateral overgrowth. Local wing tilts and their fluctuation over the sample area as well as the local and average number of grains in the wings are determined, and the reduction of threading dislocation densities in the grains of the ELO wings can be quantitatively estimated.
