py21cmmc.likelihood.LikelihoodEDGES#

class py21cmmc.likelihood.LikelihoodEDGES(use_width=False, *args, **kwargs)[source]#

A likelihood based on chi^2 comparison to Global Signal of EDGES timing and fwhm.

This is the likelihood arising from Bowman et al. (2018), which reports an absorption feature in the 21-cm brightness temperature spectra

Parameters:: use_width (bool) – whether to use the fwhm in the likelihood, by default it’s False

Methods

`__init__`([use_width])
`computeLikelihood`(model)	Compute the likelihood, given the lightcone output from 21cmFAST.
`get_fiducial_model`()	Compute and return a model dictionary at the fiducial set of parameters.
`reduce_data`(ctx)	Reduce data to model.
`setup`()	Perform post-init setup.

Attributes

`chain`	Reference to the `LikelihoodComputationChain` containing this core.
`core_primary`	The first core that appears in the requirements.
`freq_edges`
`freq_err_edges`
`fwhm_edges`
`fwhm_err_low_edges`
`fwhm_err_upp_edges`
`parameter_names`	Names of the parameters of the full chain.
