Indexing of two superimposed lysozyme diffraction patterns. (a) The primary lattice model (yellow boxes) after an initial round of refinement, where colored dots represent the spots included in the lattice refinement. Color coding is the same as used in Figs. 2 and 3. Red spots are the subset safely considered to be part of the primary lattice, while pink spots are the outliers identified by equation (6) (consistent with the visual impression). (b) The lattice that results from a second round of autoindexing using only the pink-coded outliers as data. Spot color codes are the same as in (a). The new lattice in (b) is clearly consistent with the pink (outlying) observations. |
