Analysis
A baseline correction has been performed and then the spectrum has been normalized by adjusting the height of the maximum of the Si-O band to 1 and the band minimum (Christensen feature) to 0. Some reflectance features are present for wavenumber below 350 cm-1, they are due to non perfect compensation of athmospheric contribution.
