(a) Reconstructed hk1.02 layer collected from the HE-GID experiment at ultra-small-angle grazing-incidence geometry with an SDD of 491 mm. The modulation of intensity across the frames is evinced. The sector indicated with black lines represents the asymmetric unit of the Laue group 4/mmm with the strongest intensity. (b) Symmetry-expanded hk1.02 layer using the asymmetric unit indicated in panel (a) represented in a different contrast. The magnified inset on the right shows first-order and second-order diffuse rings around the CTRs. Note that regions outside the asymmetric unit were not used; instead, the full reciprocal space was reconstructed via symmetry expansion of the indicated subvolume in panel (a) as justified by the high crystal symmetry.
