Data versus theory (a) Representation of measured data μ_d' and calculation as provided in Ref. 27 (blue line and symbols); Data and theory transformed according to ξ_GI μ_d'/2r (red crosses and green line with circles, respectively) and |(G-1)| as calculated for the samples from the theory presented here (red line) displaying full agreement proving that the calculation presented and data reduction in Ref. 27 corresponds to 2r|(G-1)|/ξ_GI; (b) Visibility data (markers) from (a) Ref. 27 and calculation (lines) presented according to equ. (18) as a function of autocorrelation length ξ_GI and sorted by sample (particle size), demonstrating good agreement between theory and data as well as the direct relation to particle size and scattering cross section (note: here represented by 2r only), both of which can be extracted straightforwardly. (Note: no error bars are given as original data in Ref. 27 is provided without error bars and any additional introduced error is considered less than the given symbol sizes).
