A C-based interface to the dust code
typedef void dust_AbsXSec |
Absorption Cross section.
Infact define as opaque pointer which is later recast to UnaryDD.
typedef double dust_pvector |
Energy bin grain probability distribution vector.
Represents the probability distribution that the grain is in a particular bin
typedef void dust_RF |
Radiation field.
Just an opaque pointer -- will need to cast it to the c++ type to make use.
