firecrown.likelihood.gauss_family.statistic.source.source.Tracer#

class firecrown.likelihood.gauss_family.statistic.source.source.Tracer(tracer, tracer_name=None, field=None, pt_tracer=None, halo_profile=None, halo_2pt=None)[source]#

Bases: object

Extending the pyccl.Tracer object with additional information.

Bundles together a pyccl.Tracer object with optional information about the underlying 3D field, a pyccl.nl_pt.PTTracer, and halo profiles.

Parameters:

  • tracer (pyccl.Tracer) –

  • tracer_name (None | str) –

  • field (None | str) –

  • pt_tracer (None | pyccl.nl_pt.PTTracer) –

  • halo_profile (None | pyccl.halos.HaloProfile) –

  • halo_2pt (None | pyccl.halos.Profile2pt) –

Public Methods:

determine_field_name(field, tracer)

Gets a field name for a tracer.

__init__(tracer[, tracer_name, field, ...])

Initialize a new Tracer based on the pyccl.Tracer which must not be None.
static determine_field_name(field, tracer)[source]#

Gets a field name for a tracer.

This function encapsulates the policy for determining the value to be assigned to the field attribute of a Tracer.

It is a static method only to keep it grouped with the class for which it is defining the initialization policy.

Parameters:

  • field (None | str) –

  • tracer (None | str) –

Return type:

str

property has_hm: bool#

Return True if we have a halo_profile, and False if not.

property has_pt: bool#

Return True if we have a pt_tracer, and False if not.
