Figure 4
Commonly encountered reciprocal-space pathologies using dials.reciprocal_lattice_viewer. (a) Problems with image headers, such as an incorrect beam centre or an inverted rotation axis, may lead to an apparent distortion in the lattice. Depending on the severity of the distortion, autoindexing may identify an incorrect lattice or result in an offset in the assigned Miller indices. (b) Visible features that are not part of the primary lattice, such as points arranged in a spherical shell, may indicate the presence of ice rings or low-quality powder samples. (c) Split crystals or multiple lattices are visible as a set of two or more intersecting lattices. Unindexed reflections and reflections identified as belonging to distinct lattices are coloured separately to aid visualization. (d) Multiple sweeps from a single crystal on a multi-axis goniometer can be combined for display, with each sweep uniquely coloured. |
