FisherLens: Fisher forecasting code for CLASS_delens

This code provides a wrapper for the CLASS_delens code to facilitate Fisher forecasting of cosmological parameter constraints from CMB spectra.

CLASS_delens https://github.com/selimhotinli/class_delens

Authors: Selim C. Hotinli, Joel Meyers, Cynthia Trendafilova, Daniel Green, Alexander van Engelen

Getting started

Download and compile the CLASS_delens submodule.

The file fisherGenerateDataClass_example.py will produce a forecast for LambdaCDM + N_eff + m_nu.

Additional python files and Jupyter notebooks can be found under paperPlots; these will replicate the figures from [arXiv number].

Using the code

This code is free to use; please cite [arXiv number] in your publications.
