CosmoSIS: The COSMOlogical Survey Inference System

CosmoSIS is a cosmological parameter estimation code. It is now at version 3.3

It is a framework for structuring cosmological parameter estimation with a focus on flexibility, re-usability, debugging, verifiability, and code sharing in the form of calculation modules. It consolidates and connects together existing code for predicting cosmic observables, and makes mapping out experimental likelihoods with a range of different techniques much more accessible.

CosmoSIS is described in Zuntz et al - if you make use of it in your research, please cite that paper and include the URL of this repository in your acknowledgments. Thanks!
