Description of the data (0.3 – 2.6 μm)
All spectra were obtained at i=30 degrees, e=0 degrees. There are an image file and a data file for each soil measured by the LSCC. Click on the image file for a larger version. Each data file contains reflectance factor spectra for all soil size fractions and a standard deviation measurement for each data point, where appropriate. Each data file contains a header line followed by nine entries of tab-delimited reflectance data (as text): Wavelength, soil <10 micrometers, standard deviation, soil 10-20 micrometers, standard deviation, soil 20-45 micrometers, standard deviation, bulk soil <45 micrometers, standard deviation (some standard deviation fields are empty).

The Lunar Soil Characterization Consortium (LSCC) has also performed detailed chemistry and modal abundance analyses on each of these samples.
