Results of the NMF analysis and spectral imaging of the CA sample.
(a) The extracted component spectra (solid lines) compared to individual spectra of selected times (points). The spectra are offset for clarity. (b) The component weights as a function of time: extracted using NMF (solid lines) and by a fitted model (dashed lines). (c) Imaging of the progression of the chemical composition in the CA crystal. Red, green and blue channel correspond to the weights of CA, TA and FP component spectrum, respectively. The X-ray beam enters the crystal from left.
