py21cmmc.likelihood.LikelihoodGlobalSignal#

class py21cmmc.likelihood.LikelihoodGlobalSignal(datafile=None, noisefile=None, simulate=False, emulate=False, use_data=True)[source]#

Chi^2 likelihood of Global Signal, where global signal is in mK as a function of MHz.

Methods

`__init__`([datafile, noisefile, simulate, ...])
`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.
`parameter_names`	Names of the parameters of the full chain.
`required_cores`
