ismdust: Extinction due to a power-law distribution of
dust grains
This model provides the extinction (= absorption + scattering) properties for a power law distribution of dust grains using the optical properties for dust provided in Draine (2003). The default mixture of 60% / 40% silicate / graphite is described in Corrales et al. (2016). Please cite this paper if you use this model.
The parameters are:
par1 | sil_md : dust mass column for silicate (in units of |
par2 | gra_md : dust mass column for graphite (in units of |
par3 | redshift : z |
