Figure 5
SADP from two overlapping twin variants related by a 90° rotation about 〈011〉 or pseudocubic 〈010〉. Horizontal ovals represent reflections from variant A, while vertical ovals are from variant B. Reflections left unmarked are common to both variants. The two variants can be indexed as [011] and [[0\bar1\bar1]] or [[0\bar11]] and [[01\bar1]], making the twin plane {211} type, with a 〈111〉 twin axis. This geometry corresponds to a pseudocubic {110} twin plane and 〈110〉 twin axis.
