Figure 8
Choice of reciprocal-space sampling grid. (a) An intensity map of a representative slice of reciprocal space with a step size of 0.026 Å−1 (1701 × 1701 × 1701 voxels). Note that, within the inset regions on an enlarged scale, portions of reciprocal space inside the maximum momentum transfer vector of the experiment contain no data (represented by red pixels among other colored pixels). (b) Similar to (a), with a step size of 0.29 Å−1 (151 × 151 × 151 voxels). The insets demonstrate that diffuse features and Bragg peaks now span the same 1–3 voxels, and would be difficult to disentangle during the punch and fill process. |
