Comparison of the filtered EXAFS signal obtained by the two methods. Continuous line: EXAFS obtained by extracting the signal, Fourier filtering and then averaging (method 1). Squares: EXAFS obtained by averaging, extracting the signal and then Fourier filtering (method 2). The two spectra are similar. The signal corresponds to the first peak of the Fourier transform shown in Fig. 3. |
