Different quality diffraction patterns calculated from a model of the Tl correlations in TlSbOGeO4 (Welberry & Mayo, 1998). (a) The three types of correlation vectors. (b) Pattern calculated from a single 10 × 10 × 10 sample taken from a larger crystal. (c) The best pattern obtainable from a crystal of 10 × 10 × 10 unit cells. (d) The best pattern obtainable from a crystal of 32 × 32 × 32 unit cells. |
