Thermophysical model of Titania between 5 and 300 μm (black line) for the second epoch (2011-07-12). Photometric measurements are PACS observations (red boxes), the IRTF observation (blue diamond) and the Spitzer-IRS CASSIS data (orange spectrum: leading hemisphere observation; red spectrum: trailing hemisphere data). For an explanation of the IRTF and IRS data re-scale, see text and caption of Fig. 7. The insert shows the resulting TPM surface temperature map of Titania for the range 40–85 K.
