Dust Grains¶
This section is started with the single line:
[Dust Grains]
Model Type¶
type=dust_model [dust_model, single_wavelength]
If dust_model, then use a wavelength grid (see below)
if single_wavelength, then specify the needed details
Note
More options possible, need to add
wavelength=0.55 [??, ??]
Wavelength in microns
albedo=0.5 [0.0, 1.0]
Single scattering albedo.
g=0.7 [-1.0, 1.0]
Henyey-Greenstein phase function asymmetry.
Wavelength Grid¶
wave_type=res [res,file]
The type of wavelength grid can be set to be either res (by resolution) or file (by an ASCII file).
wave_type=res wave_min=0.0912 wave_max=1000. wave_resolution=10.
If the wave_type is res, then the wavelength grid is defined by a min/max wavelength (in microns) and desired resolution.
wave_file=wave_grid_pah_opt.dat [string]
If the wave_type is file, then the wavelength grid is set by a a file where each line in the file is a wavelength point given in microns.
As an example, a wavelength grid optimized for normal ISM dust is given by wave_grid_pah_opt.dat. This is a grid at a resolution of 10 from 0.0912-1000 microns with an embedded higher resolution grid (resolution = 50) from (roughly) 3 to 20 microns.
