a Set of spectra at different pressures plotted in an absolute SRL scale. Legend applies to all panels. b Zoom of a showing a detail of the spectra acquired at pressures equal to 0.05 and 0.1 bar. c Residuals (data—model) normalized to the corresponding spectral maxima, obtained from a global fitting with 5 free parameters and 3 fixed to ab initio value. \({\chi }_{r}^{2}\) represents the reduced chi square of the fit. d Residuals as above, obtained from a global fitting with 2 free (\({\nu }_{0}\), \({\delta }_{0}\)) and 6 fixed parameters.
