Power spectral density (PSD) for distinct data sets obtained at different stages of particle-size filtering. (a) PSDs for the data Set_10k ^PCA of diffraction patterns. (b) PSDs after the size-distribution filtering for Set_8k ^PCA. (c) PSDs after using a restricted fit quality range for Set_7k ^PCA. (d) Histogram of positions of the first minimum from data Set_10k ^PCA used for the size filtering. Diffraction patterns inside the blue box (±1 r.m.s. around the mean value) were selected for further analysis. (e) Histogram of the PSD fit quality χ. Diffraction patterns inside the blue box ( r.m.s. around the mean value) were selected for further analysis.
