Figure 5.

A demonstration of how the optimal spot-finding parameter combinations differ between individual diffraction images. The distribution of the optimal parameter combinations over 705 successfully integrated diffraction images is shown as a heat map. Each diffraction image was indexed and integrated using every possible combination of the two spot-finding parameters; only the selected ‘best’ integration results (one per image) were used to construct the heat map. The color of each square represents the number of optimally integrated diffraction images for this combination of spot-finding parameters, also shown inside the square. Note that no dominant combination of spot-finding parameters effective for the majority of images is found by the grid search, indicating that they should be determined separately for each diffraction image.
