(a) First Medipix image of KMnO4 at two different indices at low temperature (LT = 11 K). The left-hand portion displays the image of seven crystals of the chosen sample, while the right-hand portion shows the Kapton fringe appearing at completely different indices. Here, the index refers to a consecutive sequence of emission energies. (b) Elastic scan of KMnO4 at an incident energy (Ein) of 6490.4 eV. The entire white-marked rectangular area is selected as the region of interest (RoI). The result depicts an additional bump just before the main peak, which represents the influence of the Kapton tape from our experimental setup. (c) Corrected elastic scan utilizing our standard approach for RoI selection, as discussed in this paper, effectively removing the Kapton influence.
