!# Size distribution of dust grains.
!# Model number 7 of table 1 of Weingartner & Draine (R_V = 3.1, b_c = 6*10^-5).
!# No PAHs at radius a > 10^-2 µm (Not clear if this is true in the paper, but optical
!# properties of graphites and PAHs are anyway very similar at 10^-2 µm. Moreover, the
!# neutral/ionized PAHs ratio is not given above this radius.)

!# First line: type of grain size distribution; number of dust components.

!# For each dust component, one block containing:
!# * First line: 
!#   -- number of grain sizes;
!#   -- name of the file containing the optical properties;
!#   -- .true. if carbonaceous grains, .false. otherwise.
!# * Following lines: for each size,
!#   -- grain radius `a` in µm;
!#   -- `(dn/da)/n_H` in µm-1.
