py21cmmc.likelihood.Likelihood1DPowerLightcone

class py21cmmc.likelihood.Likelihood1DPowerLightcone(*args, datafile='', nchunks=1, **kwargs)

A likelihood very similar to Likelihood1DPowerCoeval, except for a lightcone.

This likelihood is vectorized i.e., it accepts an array of astro_params, but only when used with Core21cmEMU.

Since most of the functionality is the same, please see the other documentation for details.

Methods

__init__(*args[, datafile, nchunks])
computeLikelihood(model)	Compute the likelihood given a model.
compute_power(box, length, n_psbins[, ...])	Compute power spectrum from coeval box.
from_builtin_data([datafile])	Create the class loading in built-in data.
get_fiducial_model()	Compute and return a model dictionary at the fiducial set of parameters.
reduce_data(ctx)	Reduce the data in the context to a list of models (one for each redshift chunk).
setup()	Perform post-init setup.
store(model, storage)	Store the model into backend storage.
