Figure 7
(a) SADP from two overlapping twin variants related by a {211} twin plane and a 90° rotation about 〈011〉. Horizontal ovals represent reflections from variant A oriented along 〈011〉, while vertical ovals are from variant B oriented along [100]. Reflections left unmarked are common to both variants. (b) SADP from three overlapping twin variants related by {211} twin planes. Horizontal ovals represent reflections from variant A oriented along 〈011〉; vertical ovals are from variant B oriented along [100]; and reflections marked with a circle arise from the third variant oriented opposite to variant A along 〈011〉. Reflections left unmarked are common to all three variants.
