(a) Schematical microdiffraction pattern for orthogonal superstructure parallel to 〈201〉 ([1[\bar 1]0]s) in the hypothetical case of complete 3D translation symmetry. (b) Schematical microdiffraction pattern for twinned crystal structure with orthogonal superstructure parallel to 〈201〉 ([1[\bar 1]0]s) and hence parallel to the twin plane in the case of broken 3D translation symmetry. (c) Schematical microdiffraction pattern for a body-centred tetragonal unit cell (c/a = 2) parallel to [201]. (d) Schematical microdiffraction pattern for a primitive tetragonal unit cell (c/a = 2) parallel to [201]. (e) Experimental microdiffraction pattern for twinned crystal structure parallel to 〈201〉 ([1[\bar 1]0]s).
