Simulated diffraction patterns from a two-dimensional crystal consisting of two adjacent domains separated in the b (vertical) direction. For both diffraction patterns, one domain consists of 10 × 10 lattice points with lattice dimensions a = b. The second domain consisting of 10 × 10 lattice points with a, b dimensions (left) a, 1.125a and (right) 1.125a, 1.125a. The program nearBragg (http://bl831.als.lbl.gov/~jamesh/nearBragg/) from James Holton was used for this calculation.
