Near-infrared spectra derived from different dust models; a constant γ = 3.5 is used (left panel) and A_max = 1.0μm (right panel). The red and green lines are models where the albedo of the dust grains has been changed during the scattering computations by −10% (red) or by +10% (green), and the black line is a model where only the A_max and γ were varied during the scattering computations. Each symbol (circle, triangle, square) corresponds to a different A_max and γ value in the left and right panels, respectively.
