Notes.Listed are the relative mass fractions of the forsterite components at different temperature or with different iron mass fractions. Also listed is the confidence intervals for the mass-average-temperature (M.A.T.) of the fitted dust components. The distance intervals are computed based on the ranges of dust temperature (see text).
