Extended Data Fig. 2: RSM data.
a, 3D reciprocal space map around the DSO 002pc Bragg peak. The side panels show the 2D projected intensity of the recorded scatter. b, RSM around the asymmetric reflection (103)pc. c, Reciprocal space map Qz versus Qx. d, Comparison plot of the extracted Qz scan at Qx = 0 and Qx = 0.07 Å−1. e, Integrated (boxed area) line profile showing the first-order and second-order satellite peaks and their widths. f, Reciprocal space map Qz versus Qy. g, The integrated (boxed area) line profile shows weak first-order satellite peaks corresponding to a periodicity of about 8.05 nm. h, Plan-view projection into a Qx versus Qy RSM map with extracted line scans showing the in-plane distribution of the satellite peaks.
