Effect of temperature on the peak position and FWHM of the 69 μm band. The blue crosses are based on optical constants from Suto et al. (2006) using the distribution of hollow spheres by Min et al. (2003) with a grain size of 0.1 μm. The green asterisks represent mass absorption coefficients from Koike et al. (2006). Both datasets were taken on pure forsterite.
