Left: preliminary temperature calculation on Phobos using the Gaskell shape model (Gaskell 2011). The model was reduced to 98,000 facets to speed-up calculations. Temperatures decrease from yellow to red to blue. Right: spectral radiance calculated using the thermal model and assuming that the reflected light component is a reddened solar spectrum. The spectral radiance is normalized to 1 at the peak of the curve. Notice the strong thermal tail that arises in MIRS relevant wavelengths and its strong dependence on temperature
