Dust optical depth for J13 and AMMI models relative to hydrogen column density N(H) = 1021 cm−2. The solid lines are for absorption and the dashed lines for scattering. The plot lists τ(250 μm)∕τ(J) ratios where the first number corresponds to absorption (points marked with crosses) and the second to extinction (marked with circles).
