Figure 6
Plot of the Bragg to diffuse intensity ratio as a function of spatial frequency q for various amounts of added photons to simulate background. A high ratio indicates that the orientations have been correctly identified and most of the intensity is in Bragg peaks, whereas a ratio near 1 would mean that the peaks are not resolved over background. There were 314 photons per frame in the base data set. Even with 400% background, the low-resolution peaks were resolved, as seen in the 1256 photons per frame plot. |
