class beast.physicsmodel.dust.extinction.Generalized_DustExt(curve='F04')[source]

Bases: ExtinctionLaw

Generalized extinction curve class to import classes from dust_extinction package.

Accepts class name as string input (curve) for all average and Rv-dependent parameter_averages extinction curve classes.

Methods Documentation

function(lamb, Av=1, Rv=3.1, Alambda=True, **kwargs)[source]

Generalized Extinction Law

Parameters:

  • lamb (float or ndarray(dtype=float)) – wavelength [in Angstroms] at which to evaluate the law.

  • Av (float) – desired A(V) (default 1.0)

  • Rv (float) – desired R(V) (default 3.1) ignored if self.hasRvParam=False; defaults to self.Rv

  • Alambda (bool) – if set returns +2.5*1./log(10.)*tau, tau otherwise

Returns:

r – attenuation as a function of wavelength depending on Alambda option +2.5*1./log(10.)*tau, or tau

Return type:

float or ndarray(dtype=float)
