Optical constants and absorption efficiencies for olivine and iron of Pollack et al. (1994), and for amorphous carbonaceous grains from the “BE” sample of Zubko et al. (1996) used in this paper, in addition to the data introduced by Dikarev et al. (2009). The absorption efficiencies are calculated for the sizes of spherical dust grains indicated in the bottom row of plots.
