Notes. Results for an unsettled dust size distribution with amin = 0.05 μm, amax = 3 mm, apow = 3.5, grain material density ρgr = 2.094 g cm−3, gas-to dust ratio 100, and gas density n〈H〉 = 1010 cm−3, using Nbin = 4. The consecutive lengths are calculated as āj nd,j, the surface areas as 
, and the volumes as 
. The correct total values are marked in bold: nd = 1.78 × 10−4 cm−3, length = 1.48 × 10−9 cm−2, area = 2.76 × 10−13 cm−1, and volume = 1.12 × 10−16.
