Detailed Description

Dust model.

This class supports both arbitrary, table-based opacity models as well as fixed power laws. The underlying model is set at construction but can be changed during use; cf. setModel(). Table-based models are evaluated via cubic spline interpolation of the logarithm of the opacity.

Note

Once initialized, a model may be safely shared among multiple threads.

Constructor & Destructor Documentation

Dust() [1/2]

manticore::Dust::Dust ( const std::string &  model = "OH5", double  rho = 100.0  )

inline

Default constructor.

Parameters

[in]	model	Dust model name.
[in]	rho	Gas-to-dust ratio.

Definition at line 33 of file Dust.h.

References rho(), and setModel().

~Dust()

manticore::Dust::~Dust ( )

inline

Destructor.

Definition at line 37 of file Dust.h.

References spline_.

Dust() [2/2]

manticore::Dust::Dust ( double  lamb0, double  kappa0, double  beta  )

inline

Fixed power-law constructor.

Member Function Documentation

kappa()

double manticore::Dust::kappa

(

double

nu

)

const

Gas/dust extinction opacity (cm^2/g).

Parameters

[in]

nu

Observation frequency (Hz).

The opacity value is interpolated from tabulated values assuming a fixed power law dependence between adjacent points. If nu lies woutside the range of the table, the corresponding end value is extrapolated.

Returns

Dust+gas extinction opacity at the given wavelength.
