Figure 7
Determination of metric symmetry from a single oscillation image as a function of the input beam position. The true beam position is indicated by a black dot. Green pixels indicate correct determination of rhombohedral symmetry, while yellow denotes input parameters that incorrectly lead to a monoclinic C-centered lattice, and cyan denotes a triclinic lattice. Grey pixels indicate that no indexing is possible. Method A (§2.8) was used to determine symmetry in panel (a), while method B was used in panel (b). |
