Figure 5
Performance of center detection methods on representative polycrystalline diffractograms corresponding to Fig. 2. Column 1: 1D radially averaged profiles computed using each method's center (overlaid, color coded). Column 2: enlargement of the dominant peak (red box in Column 1), showing the top-performing method(s). Column 3: original diffractogram with detected centers (color-coded crosses). Column 4: enlargement of the central region (blue box in Column 3) around the direct (primary) beam and the detections. Samples: (a) and (e) Au nano-islands, (b) Ag crystals, (c) Fe3O4 nanoclusters, and (d) ZnO–CuO nanoparticles.
