hmf.transfer_models

Models for computing the transfer function.

Note that these are not transfer function “frameworks”. The framework is found in transfer.

Base Component(s)

TransferComponent(cosmo, **model_parameters)

Base class for transfer models.

Models

BBKS(cosmo, **model_parameters)	BBKS (1986) transfer function.
BondEfs(cosmo, **model_parameters)	Transfer function of Bond and Efstathiou, in the shape-parameter form of EBW92.
CAMB(*args, **kwargs)	Transfer function computed by CAMB.
CLASS(*args, **kwargs)	Transfer function computed by CLASS.
EH(*args, **kwargs)	Alias of EH_BAO.
EH_BAO(*args, **kwargs)	Eisenstein & Hu (1998) fitting function with BAO wiggles.
EH_NoBAO(*args, **kwargs)	Eisenstein & Hu (1998) fitting function without BAO wiggles.
FromArray(*args, **kwargs)	Use a spline over a given array to define the transfer function.
FromFile(*args, **kwargs)	Import a transfer function from file.

Functions

check_boltzmann_cosmology(cosmo, name)	Raise an error if a Boltzmann code (CAMB, CLASS) cannot compute cosmo.
class_cosmology(cosmo)	The CLASS input parameters that describe an astropy cosmology.
