The grey bands indicate the standard deviation. The measured data are compared with theoretical DFT calculations, for which we used a smearing width of 7 eV for Fe2O3 and 9 eV for Fe47. The insets show the reconstruction of the M-shell vacant states, located around -55 eV. This feature is only present if the M-shell is thermally ionized by the x-ray beam, thus allowing us to estimate the temperature of the sample. The red dashed vertical line indicates a reference M-shell binding energy, taken from27.
