Error calculations: (A) the percentage difference maps for Fe K, Zn K, Gd L3, Gd L2, and Gd L1, calculated by subtracting the map from full-spectral fitting from the maps created using the 70% threshold (Fig. 6[link]), and dividing by the maximum pixel value for that image. (B) The percentage residuals from (A) were histogrammed and the resulting histograms were fitted to a Gaussian function to calculate the % standard error between full-spectral fitting and abridged spectral fitting. (C) The fitted value for the Gaussian functions calculated in (B) with 95% confidence bounds.
