F19_D03_extension

class beast.physicsmodel.dust.extinction_extension.F19_D03_extension(Rv=3.1, **kwargs)[source]

Bases: F19

dust_extinction.parameter_averages.F19 model extended to shorter wavelengths using the dust_extinction.grain_models.D03 models.

Parameters:

None

Raises:

  • InputParameterError – Input Rv values outside of defined range

evaluate(x, Rv)[source]

F19_D03_extension function

Parameters:

x (float) –

expects either x in units of wavelengths or frequency or assumes wavelengths in wavenumbers [1/micron]

internally wavenumbers in inverse micron are used

Returns:

axav – A(x)/A(V) extinction curve [mag]

Return type:

np array (float)

Raises:

ValueError – Input x values outside of defined range
