Nili Fossae TES-derived daytime thermal inertia versus normalized olivine abundance. (left column) Density plots and (second to fourth columns) binned thermal inertia data with average olivine abundance, for the three ROIs in Figure 2 using only limited seasonal TES data (Figure 7). The density plots are generally unchanged from the all-data case (Figure 3) with all ROIs displaying a wide range of thermal inertias for nearly all olivine abundances, but some small changes are apparent (compare to Figure 3). The binned data (Figure 8, second to fourth columns) indicate however that the general relationship between thermal inertia and olivine abundance did not change. The large and small ROIs still show a generally positive correlation between thermal inertia and olivine abundance, while the medium ROI does not (compare to Figure 3).
