(a) Anisotropic difference scattering signals extracted from the 2D scattering patterns in Fig. 4(d)[link] as a function of number of azimuthal bins. A significant decrease in the intensity of the signal is observed when decreasing the number of azimuthal bins below 5. (b) The red dots show the difference (ζ) between P2 calculated as the central value in the azimuthal bins or as in equation (14)[link]: [\zeta] = [\langle P_{2}(\cos\theta_{Q})\rangle_{2\delta\varphi}] − [P_{2}(\cos\theta_{Q})] = [({{3}/{4}})\cos^{2}\theta\cos2\varphi[1-({{\sin2\varphi}/{2\delta\varphi}})]]. With respect to this, the blue dots show the resulting difference (∊) in the magnitude of [\Delta S_{2}] (at Q = 2 Å−1): [\varepsilon] = [(\langle\Delta S_{2}\rangle_{2\delta\varphi}] − [\Delta S_{2})/\langle\Delta S_{2}\rangle_{2\delta\varphi}]. The dashed black line shows the averaged experimental uncertainty [\sigma_{\Delta S_{2}}] (divided by the measured signal).
