Notes.
Opacities from Jaeger et al. (1994), Dorschner et al. (1995).
Modified Curve No. 22 of Ossenkopf & Henning (1994) using submm-β = 1.99, but normalized at 100 μm, i.e. β350−100 μm = 2.18.
M = 59.1 M⊙: unmodified BARE-GR-S assumes g2d = 161 (Zubko et al. 2004).
M = 38.0 M⊙: RV = 5.5 curve of Weingartner & Draine (2001) that includes PAHs assumes g2d = 105.1.
