Spectral data associated to the publication: "VIS spectroscopy of NaCl - water ice mixtures irradiated with 1 and 5 keV electrons under Europa's conditions: Formation of colour centres and Na colloids " by R. Cerubini et al. (Icarus 379, 2022)

This is the complete set of experimental VIS reflectance data collected by R. Cerubini and co-authors for the article "VIS spectroscopy of NaCl - water ice mixtures irradiated with 1 and 5 keV electrons under Europa's conditions: Formation of colour centres and Na colloids" published in Icarus 379 (2022). doi: https://doi.org/10.1016/j.icarus.2022.114977.

The article itself is published in open-access and provides the methodology for the spectral aquisitions, discussion of the errors and uncertainties, analysis of the spectra and implications for the composition of Solar System surfaces.

The data are contained in ASCII files (columns separated by comma). The first column is the wavelength (in micrometers) and the other columns contain the reflectance data (in unit of reflectance factor). The different compositions are indicated in the filenames and correspond directly to the figures in the published paper.
