Fisher forecasts with 21cm experiments
Project description
21cmCAST
This package provides tools to perform Fisher foreCASTs from 21cmFAST outputs. It has been built on / complementarily to the 21cmFish package[^1]. A detailed example of how it works can be found in scripts/exec/fisher.ipynb.
In order to work properly, the codes requires to have a working installation of
If you are considering using this code, please cite the following work for which it has been developped
- G. Facchinetti, L. Lopez-Honorez, Y. Qin, A. Mesinger, 21cm signal sensitivity to dark matter decay [arXiv:2308.16656]
Installation
In order to install the code you can install it with pip running
pip install py21cmcast
In order to use and modify the code clone this repository and run
pip install -e .
in the main folder.
Quick start guide

Ongoing work
To do list:
- rearrange the code in a self-contained package
- uniformely use astropy units throughout the entire code
- add docstrings to the classes
