py21cmcast 1.0.1

Fisher forecasts with 21cm experiments

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

• 21cmFAST[^2][^3]
• 21cmSense[^4]

If you are considering using this code for you own work, please cite

• G. Facchinetti, L. Lopez-Honorez, A. Mesinger, Y. Qin (in prep.)

To do list:

• rearrange the code in a self-contained package
• uniformely use astropy units throughout the entire code
• add docstrings to the classes
