Crystal shape variations do not reduce the recovered molecular transform qualities. The fraction of boundary that is covered by partial unit cell is the determining factor for the recovered unit-cell patterns. The fractions are 0.2, 0.5, 0.8 for (a), (b), (c), correspondingly. The numbers shown in the lower right corners are the R factors compared with the theoretical unit-cell transform, relative to the default unit cell; and the values in parentheses are the R factors compared with the alternative unit-cell transform (see Fig. 2h).
