Introduction

Firecrown is a Python package that provides the DESC framework to implement likelihoods, as well as specific likelihood implementations. Firecrown is intended to be usable from external statistical analysis tools.

Currently, it supports both Cobaya and CosmoSIS, providing the necessary classes or modules to allow users of Cobaya or CosmoSIS to call any Firecrown likelihood from within those samplers.

• Cobaya

• CosmoSIS

It can also be used as a library in other contexts, and so the installation of Firecrown does not require the installation of a sampler.
