Diffraction rastering of multiple polygons. (a) A clear view of the sample after centering. (b) The user outlined each of several potential crystals with a polygon. The polygons were filled with cells of user-defined size that is matched to the selected 20 µm mini-beam. In the process of rastering, the sample is translated to center each cell in the grid at the beam position and a diffraction image is recorded. In this case, image processing is enabled and the results table is populated with quality indicators for each cell. Only `Spot Total' is shown here; other quality indicators can be viewed by moving the slide bar to the right, and column widths can be adjusted to keep the user-favored quality indicator in view. Each cell in the sample viewer is colored according to the user-selected quality indicator on the left. Note that run parameters (lower left) cannot be changed after the rastering run is started.
