All images are 1096 samples by 1779 lines.  ISIS files are single band floating point data with most significant bit (MSB) first.

Large elevation changes interfere with the atmospheric correction in THEMIS data.  All concentration maps have been limited to elevations higher than -1650m.

Image files:

olivine_basalt_conc - Concentration of olivine basaltic spectral endmember.  This is a spectral endmember simlar in shape to surface type 1.

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.
