Spectra of the disk radiative transfer model as observed under different disk inclinations for the M15 ice and core composition and different dust size distributions. Distributions correspond to, from the top left to the lower right: silicates core, M15 ice mantle composition and size distribution MRN, a_max = 0.25 µm (model #4); τ₁, a_max = 1 µm (model #5); τ₃, a_max = 3 µm (model #6); τ₃, a_max = 3 µm (model #6) with the ice threshold is set at instead of 3; and a_max = 5 µm (model #7).
