Figure 2
(a) The modulus of a two-dimensional CSD. The dashed lines represent the integration paths for different Δx in equation (8)

. (b) The normalized CSD modulus along the respective dashed lines in (a). (c) The resulting modulus of the normalized ICSD curve |G(Δx)/G(0)|. G(Δx) is obtained by integrating the CSD profiles shown in (b).
