Interface to candl.

Assumptions

• candl python module

Setup Parameters

Name	Type	Default	Description
data_set	str		The data set to use
variant	str	None	Variant of the data set requested, if applicable.
lensing	bool	True	Lensing likelihood (or primary CMB).
feedback	bool	True	Whether to generate feedback from the likelihood initialisation.
data_selection	any	…	Further data selection
clear_1d_internal_priors	bool	True	Delete all 1d Gaussian priors implemented in candl.
clear_nd_internal_priors	bool	False	Delete all >1d Gaussian priors implemented in candl. Beware: CosmoSIS does not have support for higher-dimensional Gaussian priors.
force_ignore_transformations	str	None	Backdoor to explicitly ignore certain transformations in the data model. See candl documentation for more information.

Input values
