G03_SMCBar_WD01_extension

class beast.physicsmodel.dust.extinction_extension.G03_SMCBar_WD01_extension(*args, meta=None, name=None, **kwargs)[source]

Bases: G03_SMCBar

dust_extinction.averages.G03_SMCBar model extended to shorter wavelengths using the dust_extinction.grain_models.WD01 SMCBar model.

Parameters:

Rv (float) – R(V) = A(V)/E(B-V) = total-to-selective extinction

Raises:

  • InputParameterError – Input Rv values outside of defined range

Methods Documentation

evaluate(x)[source]

G03_SMCBar_WD01_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
