firecrown.models.cluster.kernel

The cluster kernel module.

This module holds the classes that define the kernels that can be included in the cluster abundance integrand.

Classes

`KernelType`	The kernels that can be included in the cluster abundance integrand.
`Completeness`	The completeness kernel for the numcosmo simulated survey.
`Purity`	The purity kernel for the numcosmo simulated survey.
`TrueMass`	The true mass kernel.
`SpectroscopicRedshift`	The spec-z kernel.

class firecrown.models.cluster.kernel.KernelType(*args, **kwds)[source]

Bases: enum.Enum

The kernels that can be included in the cluster abundance integrand.

class firecrown.models.cluster.kernel.Completeness[source]

The completeness kernel for the numcosmo simulated survey.

This kernel will affect the integrand by accounting for the incompleteness of a cluster selection.

distribution(mass, z)[source]

Evaluates and returns the completeness contribution to the integrand.

Parameters:

Return type:

numpy.typing.NDArray[numpy.float64]

class firecrown.models.cluster.kernel.Purity[source]

The purity kernel for the numcosmo simulated survey.

This kernel will affect the integrand by accounting for the purity of a cluster selection.

distribution(z, mass_proxy, mass_proxy_limits)[source]

Evaluates and returns the purity contribution to the integrand.

Parameters:

Return type:

numpy.typing.NDArray[numpy.float64]

class firecrown.models.cluster.kernel.TrueMass[source]

The true mass kernel.

Assuming we measure the true mass, this will always be 1.

distribution()[source]

Evaluates and returns the mass distribution contribution to the integrand.

We have set this to 1.0 (i.e. it does not affect the mass distribution)

class firecrown.models.cluster.kernel.SpectroscopicRedshift[source]

The spec-z kernel.

Assuming the spectroscopic redshift has no uncertainties, this is akin to multiplying by 1.

distribution()[source]

Evaluates and returns the z distribution contribution to the integrand.

We have set this to 1.0 (i.e. it does not affect the redshift distribution)
