a, b GIWAXS of lightly sheared film of FCN16 in Col (130 °C) and Fddd (100 °C) phases, respectively; note the absence of the 3.5 Å streak in Col phase. c, d qxy (vertical) and qz (horizontal) scans of the 3.5 Å streak in b; in c the peak is reflected across the horizon to facilitate curve resolution. e Reciprocal space description of diffraction geometry in b, showing symbolically a SAXS ring and the 3.5 Å disks cut by the Ewald diffraction sphere.
