Comparison of dust properties for the three different grain types in this study. The top panel shows that the opacity of the Rv=5.5 grains is higher in the near-IR. The middle panel shows that both Rv=5.5 and KMH grains are more forward-throwing than the MRN grains (g is the average cosine of the scattering angle). The bottom panel shows that Rv=5.5 grains have a higher albedo than KMH which has a higher albedo than MRN. Thus the image sizes and fluxes are likely to be larger for the Rv=5.5 and KMH grains. However, the amount of direct light will be lower for Rv=5.5 grains because of its higher opacity. The MRN grains have a steeper wavelength dependence for both g and albedo, which accounts for its bluer images.
