DXP binned and fitted analyses of Ca and K. Images produced by binned analyses for K (a) and Ca (b), and by fitted analyses for K (d) and Ca (e). Overlay images of Ca (red) and K (blue) from binned (c) and fitted (f) analyses. (g) The correlation plot of binned Ca as a function of fitted Ca with data regions separated using expectation maximization, a Gaussian mixture-based soft clustering method. (h) The reconstructed image from (g). (i) Bar plot of [Ca] in the three regions obtained from binning and fitting analyses, in units of µg cm−2. Length scale bars are 500 µm.
