Dust grain density distributions for carbonaceous (solid lines) and silicate (dotted lines) dust from WD01. Thick lines are for the LMC model with ﹩R_{V}=2.6,\ b_{\mathrm{C}\,}=1\times 10^{-5}﹩, and thin lines are for the Galactic model with ﹩R_{V}=3.1,\ b_{\mathrm{C}\,}=6\times 10^{-5}﹩. For clarity, and to allow the reader to estimate the mass present in each size range, data are plotted in units of ﹩a^{4}\ dn_{gr}/ da﹩. The dot‐dashed line shows the corresponding density distribution from Mathis et al. (1977).
