TXM XANES wizard analysis of the edge energy distribution as described in §6.3[link], performed for the sample introduced in Fig. 4[link]. The histogram of edge energies versus pixel number for all pixels within the FOV is displayed using (a) logarithmic scale and (b) linear scale and was used to manually pool pixels with similar XANES edge-energy positions. The distribution of the clustered pixels within the FOV is shown in (c). The normalized sums of the XANES of all pixels of the same cluster are shown in (d). The XANES of the blue cluster is not displayed here as this cluster contains only a few pixels showing very low edge energies. These pixels have been classified as outliers.
