Frequency-dependent opacities and blackbody spectra for Tdisk = 300 K and T⋆ = 5800 K. Opacities are absorption (blue pluses), scattering (red crosses) and extinction (black dots) coefficients for the dust-and-gas mixture used in the Pasccuci test. The table contains 61 frequency bins and dataare taken from Draine & Lee (1984). Apart from the broad opacity features at about 10 and 20 μm, which correspond to Si-O vibrational transitions, the opacity generally increases with the photon frequency. The opacity at stellar-like radiation frequencies is generally greater than at disk-like radiation frequencies.
