Figure 9
Linear least-squares fitting of the pre- and post-edge intervals (indicated by blue points) of C 1s, O 1s and F 1s edges NEXAFS spectra with respect to the best-found composition of the elemental array a. Fitting is presented for four different areas: (a) non-damaged, (b) pad 3, (c) pad 7 and (d) pad 9. The spectra of all 9 pads are presented in Fig. S5. Note the vertical scale differs for each pad. |
