plima.backends.ccl#

CCL backend helpers for PLIMA intrinsic alignment models.

plima.backends.ccl.build_ccl_ia_model(cosmo, model_name, z, **kwargs)[source]#

Build CCL backend objects for a registered PLIMA IA model.

Parameters:

  • cosmo (Any) – CCL cosmology object. This is used by models that build custom Pk2D spectra. It is accepted for all models so the public API stays stable.

  • model_name (str) – PLIMA model name or alias.

  • z (ArrayLike) – Redshift values used by the IA model.

  • **kwargs (Any) – Model keyword arguments.

Returns:

Standard CCL IA model dictionary.

Raises:

  • ValueError – If the registered model family has no CCL builder.

  • KeyError – If model_name is not registered in PLIMA.

Return type:

CCLIAModel
