Detailed experimental conditions for the coating experiments of basalts.
(See note on viewing and downloading files.)

Spectra files (.asc) are given in units of wavenumber (first column) and either emission or reflectance (second column; valid values ranging from 0 to 1). See accompanying manuscripts (above) for details on useful spectral ranges in each spectral data set.
