Analysis of the z-dependency of the correlations based on the data averaged over the angular domain. z-dependent correlation for various values of r (a). The black dashed line indicates the average dipole height, cf. Eq. (109). The gray dash-dotted lines indicate peaks due to re-entrance of in-plane self-correlation through the periodic domain. The ordinate uses a logarithmic scale which transitions into a linear scale for values smaller than 2. Coefficients of the exponential fitting dependent on the radial in-plane distance r (b). Error e in the exponential fitting according to Eq. (111) (c)
