synthesizer.emission_models.operations

A submodule containing the operations performed by an EmissionModel.

An emission models inherits each of there opertaion classes but will only ever instantiate one. This is because operations are isolated to one per model. The correct operation is instantiated in EmissionMode._init_operations.

These classes should not be used directly.

class synthesizer.emission_models.operations.Generation(generator, lum_intrinsic_model, lum_attenuated_model)

A class to define the generation of spectra.

This can be used either to generate spectra for dust emission with the intrinsic and attenuated spectra used to scale the emission or to simply get a spectra from a generator.

generator

The emission generation model. This must define a get_spectra method.

Type:

EmissionModel

lum_intrinsic_model

The intrinsic model to use deriving the dust luminosity when computing dust emission.

Type:

EmissionModel

lum_attenuated_model

The attenuated model to use deriving the dust luminosity when computing dust emission.

Type:

EmissionModel

class synthesizer.emission_models.operations.Transformation(transformer, apply_to)

A class to define the transformation of an emission.

A transformation can include attenuation of the spectra by an extinction curve, or it can involve any scaling of the emission.

A Transformer is needed to apply the transformation to the emission. This class must inherit from the Transformer base class (defined in emission_models/transformers/transformer.py) and must define the get_transformation method. This method should return an array the size of the input that can multiply the emission.

transformer

The transformer to apply to the emission.

Type:

Transformer

apply_to

The model to apply the transformer to.

Type:

EmissionModel

transformation_to_hdf5(group)

Save the transformation model to an HDF5 group.
