Comparison of the LGPAR [a.u.] (orange), true alignment parameter [\alpha_{{\ell,k}}], equation (7)[link], in cm−2 (blue scatter dot), and alignment parameter estimation (APE), equation (9)[link], in cm−2 (green and red), for simulated data. The red APE is computed using the true density profile and the green APE with a constant density profile. (a) The four quantities are plotted against 36 horizontal off-center distances xc ∈ [0, 175] µm. (b) The LGPAR and the estimated alignment parameter are plotted against the true parameter. The orange solid line represents the fitted model, and the red and green solid lines are, respectively, the 1:1 and 2:1 curves to guide the eye. The estimated [\hat{\alpha}_{k}] and true alignment parameter [\alpha_{{\ell,k}}] are linearly correlated and the LGPAR exhibits a non-linear correlation with the true alignment parameter α.
