class firecrown.likelihood.cmb.CMBConvergence(*, sacc_tracer, scale=1.0, z_source=1100.0)

Bases: firecrown.likelihood.source.Source

Source class for CMB convergence lensing.

Parameters:

• sacc_tracer (str)

• scale (float)

• z_source (float)

sacc_tracer

scale = 1.0

z_source = 1100.0

Return type:

None

get_scale()

Return the scale for this source.

Return type:

float

create_tracers(tools)

Create the CMB convergence tracer.

Parameters:

tools (firecrown.modeling_tools.ModelingTools)

classmethod create_ready(sacc_tracer, scale=1.0, z_source=1100.0)

Create a CMBConvergence object ready for use.

Parameters:

• sacc_tracer (str)

• scale (float)

• z_source (float)

Return type:

CMBConvergence

class firecrown.likelihood.cmb.CMBConvergenceFactory(/, **data)

Bases: pydantic.BaseModel

Factory class for CMBConvergence objects.

Parameters:

data (Any)

model_config

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].

type_source: firecrown.metadata_types.TypeSource

z_source: float = 1100.0

scale: float = 1.0

model_post_init(_, /)

Initialize the CMBConvergenceFactory.

Return type:

None

create(inferred_galaxy_zdist)

Create a CMBConvergence object with the given inferred galaxy z distribution.

Parameters:

inferred_galaxy_zdist (firecrown.metadata_types.InferredGalaxyZDist) – the inferred galaxy redshift distribution

Returns:

a fully initialized CMBConvergence object

Return type:

CMBConvergence

create_from_metadata_only(sacc_tracer)

Create a CMBConvergence object from metadata only.

Parameters:

sacc_tracer (str) – the name of the tracer

Returns:

a fully initialized CMBConvergence object

Return type:

CMBConvergence
