(a) The location of the primary peak, $q_{\text{p}}$, (b) expected reflected wavelength, ${\lambda }_{\text{calc}}$, as calculated by eqn (2), and (c) the full width half max of the primary peak. Values calculated along the gradient direction in the 2–3 plane and vorticity direction in the 1–3 scattering plane. Error bars represent the standard error reported by OriginPro for the fitted Gaussian peaks.
