Figure also highlights the presence of 00ℓ spots observed in some, but not all, spatially resolved diffraction patterns (dashed green rectangles). These 00ℓ spots are a defining characteristic of well-ordered end-to-end chain packing in lamellar domains as illustrated earlier in Figure . We have ruled out variation in the intensities of the 00ℓ spots due to orientation changes based on comparison with electron diffraction simulations (Figure ).
