Image files:

basalt_conc - Concentration of basaltic spectral endmember.  This is a spectral endmember similar to a shape in-between surface types 1 and 2.  The distribution corresponds with the "Basalt 1" TES-derived mineralogical composition and THEMIS image endmember.

olivine_conc - Concentration of olivine spectral endmember.  The distribution corresponds with the "Basalt 2" TES-derived mineralogical composition and THEMIS image endmember.  "Basalt 2" may be modeled as a combination of "Basalt 1" plus olivine, therefore the olivine concentration map is representative of the "basalt 2" distribution.

dust_conc - Concentration of surface dust spectral endmember.

blackbody_conc - Concentration of blackbody, which can account for variable surface texture/particle size.

rms_fit_error - RMS error in emissivity fitting of the THEMIS spectra.

All concentration values are relative to the spectral contrast of the end-members used for the spectral fitting.  These values are somewhat arbitrary and should be only interpreted in a relative manner within a given concentration image.
