Methods Summary

__call__(*inputs[, model_set_axis, ...])

Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.

extinguish(x[, Av, Ebv])

Calculate the extinction as a fraction

Attributes Documentation

Methods Documentation

__call__(*inputs, model_set_axis=None, with_bounding_box=False, fill_value=nan, equivalencies=None, inputs_map=None, **new_inputs)

Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.

extinguish(x, Av=None, Ebv=None)[source]

Calculate the extinction as a fraction

Parameters
x: float

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

internally wavenumbers are used

Av: float

A(V) value of dust column Av or Ebv must be set

Ebv: float

E(B-V) value of dust column Av or Ebv must be set

Returns
frac_ext: np array (float)

fractional extinction as a function of x
