FoVBackgroundModel

class gammapy.modeling.models.FoVBackgroundModel(spectral_model=None, dataset_name=None)

Bases: gammapy.modeling.models.core.ModelBase

Field of view background model

The background model holds the correction parameters applied to the instrumental background attached to a MapDataset or SpectrumDataset.

Parameters

type

Methods Documentation

contributes(*args, **kwargs)

FoV background models always contribute

copy(**kwargs)

Copy SkyModel

evaluate(energy)

Evaluate model

evaluate_geom(geom)

Evaluate map

freeze(model_type='spectral')

Freeze model parameters

classmethod from_dict(data)

Create model from dict

Parameters

datadict

Data dictionary

classmethod from_parameters(parameters, **kwargs)

Create model from parameter list

Parameters

parametersParameters

Parameters for init

Returns

modelModel

Model instance

reassign(datasets_names, new_datasets_names)

Reassign a model from one dataset to another

Parameters

datasets_namesstr or list

Name of the datasets where the model is currently defined

new_datasets_namesstr or list

Name of the datasets where the model should be defined instead. If multiple names are given the two list must have the save length, as the reassignment is element-wise.

Returns

modelModel

Reassigned model.

reset_to_default()

Reset parameter values to default

to_dict(full_output=False)

Create dict for YAML serialisation

unfreeze(model_type='spectral')

Restore parameters frozen status to default
