We disclose the data relevant to the publication associated to this DOI. 

The details of the quantities are reported in the attached files.

Fig3-> panel Fig 3B-C are the ellipsometric data for the sample.
-> panel Fig 3D are the linear dielectric constant (complex, in column B) and the time-resolved dielectric constants as a function of time (in column A in ps) for four different pump intensities (C, D, E and F).

Fig3 - Panel General: all the information required to reconstruct figure 3. Other panel: spectrograms with wavelength and time axes reported in the panel “General”. The panel titles indicate the carrier wavelength and the pump intensity.
