(a) Comparison of the experimental data. Upper part: Intensity scale normalized to the shallow core levels (Sr 4p). (Lower part) Normalization to maximum intensity reveals identical lineshapes. (b) Simulation of the spectra, including a smooth background coming from the main valence band, two Voigt peaks (for localized and delocalized states respectively) and the Fermi edge.
