Regolith simulant dataset under simulated terrestrial and extraterrestrial conditions, Laser-induced Breakdown Spectroscopy

Spectra for each sample are provided in an individual folder with the path as Condition\simulants (for example, Earth\Mars samples) and labeled by their corresponding names (found in the files with concentrations) XYName.txt. Their corresponding XRF composition results are listed in files Mars concentrations.txt and Moon concentrations.txt together with the ratios and samples used for the new created samples in the file Mixed regoliths ratios.docx. Spectral information per sample consists of 100 spectra. In the LIBS spectra, each .txt file is organized in column orientation with 101 columns separated by a tab: the first column represents the wavelength values, and each consecutive column represents individual spectra. Hence second column is for the first spectrum, the sixth column for the fifth spectrum, and so on. Together with the spectra files of the samples, there is a reference spectrum of the reference regolith pellet, labelled as Reference_xy.txt. The file orientation is the same, but only with 10 spectra. The order in which the samples and reference were measured is in the file Sample_information.txt in each Condition folder.
