Figure 2
The six possible variants for indexing a f.c.c. lattice are obtained from Table 9 on p. 14 of the supplementary material. The corresponding matrix equation M (see supplementary material, pp. 3–8) to obtain the indices in the reindexed pattern is shown in the top-left corner of each pattern. For comparison, each pattern has been drawn so that the reciprocal lattice vector A points to the north, and the spot indices A and B of the standard setting are labeled with stars. |
