Standard dust model for N_H = 10²⁰ H cm^-2: NIR-UV extinction (top left), IR extinction (top right), albedo (bottom left) and the full dust SED (bottom right). The grain types are: a-Sil_Fe/a-C core/mantle grains (triple dot-dashed), a-C:H/a-C core/mantle grains (dotted) and small a-C grains (dash-dotted). In each plot the totals are shown by the solid lines (red). The extinction data in the upper figures are taken from Mathis (1990). The observational data in the lower right plot are: ~5–15 μm ISOCAM/CVF ISO spectrum, ~100–1000 μm FIRAS/COBE spectrum, 3.3 μm AROME narrow band measurement (triangle) and DIRBE/COBE photometry (squares) (for details see Compiègne et al. 2011).
