Thermal emission spectra of terrestrial alkaline rocks

<p>These thermal emission spectra were collected at Arizona State University. The samples and spectral collection methods are described in:</p> <p>Dunn, T. L., McSween, H. Y., &amp; Christensen, P. R. (2007). Thermal emission spectra of terrestrial alkaline volcanic rocks: Applications to Martian remote sensing. Journal of Geophysical Research E: Planets, 112(5), 1&ndash;18. https://doi.org/10.1029/2006JE002766</p> <p>This repository includes the original spectra as well as spectra that have had minor corrections for a negative spectral slope. The negative spectral slope can arise if sample temperatures change during spectral acquisition. Only two samples (49012, 49098) were slope-corrected.</p> <p>The plot shows the spectra in the *spectra.txt files. The first column in the data files (not the label files) is the wavenumber (cm-1) x-axis. The remaining columns are the emissivity spectra. The label files give the spectrum labels.</p>
