firecrown.likelihood.gauss_family.statistic.source.source.Source#

class firecrown.likelihood.gauss_family.statistic.source.source.Source(sacc_tracer)[source]#

An abstract source class (e.g., a sample of lenses).

Parameters:

systematics (list of str, optional) – A list of the source-level systematics to apply to the source. The default of None implies no systematics.
sacc_tracer (str) –

Public Methods:

`__init__`(sacc_tracer)	Create a Source object that uses the named tracer.
`read`(sacc_data)	Read the data for this source from the SACC file.
`get_scale`()	Abstract method to return the scales for this Source.
`create_tracers`(tools)	Create tracers for this Source, for the given cosmology.
`get_tracers`(tools)	Return the tracer for the given cosmology.

Inherited from Updatable

`__init__`([parameter_prefix])	Updatable initialization.
`__setattr__`(key, value)	Set the attribute named `key` to the supplied value.
`set_parameter`(key, value)	Sets the parameter to the given value.
`set_internal_parameter`(key, value)	Assure this InternalParameter has not already been set, and then set it.
`set_sampler_parameter`(value)	Assure this SamplerParameter has not already been set, and then set it.
`update`(params)	Update self by calling to prepare for the next MCMC sample.
`is_updated`()	Determine if the object has been updated.
`reset`()	Reset the updatable.
`required_parameters`()	Returns a RequiredParameters object.
`get_derived_parameters`()	Returns a collection of derived parameters.

Private Methods:

`_read`(sacc_data)	Abstract method to read the data for this source from the SACC file.
`_update_source`(params)	Method to update the source from the given ParamsMap.
`_update`(params)	Implementation of Updatable interface method _update.

Inherited from Updatable

`_update`(params)	Method for auxiliary updates to be made to an updatable.
`_reset`()	Abstract method implemented by all concrete classes to update self.
`_required_parameters`()	Return a RequiredParameters object containing the information for this class.
`_get_derived_parameters`()	Returns the derived parameters of an implementation.

abstract _read(sacc_data)[source]#

Abstract method to read the data for this source from the SACC file.

final _update(params)[source]#

Implementation of Updatable interface method _update.

This clears the current hash and tracer, and calls the abstract method _update_source, which must be implemented in all subclasses.

_update_source(params)[source]#

Method to update the source from the given ParamsMap.

Any subclass that needs to do more than update its contained Updatable objects should implement this method.

abstract create_tracers(tools)[source]#

Create tracers for this Source, for the given cosmology.

abstract get_scale()[source]#

Abstract method to return the scales for this Source.

final get_tracers(tools)[source]#

Return the tracer for the given cosmology.

This method caches its result, so if called a second time with the same cosmology, no calculation needs to be done.

final read(sacc_data)[source]#

Read the data for this source from the SACC file.
