Constraining and Restoring iterative Algorithm for Faraday Tomography

CRAFT: Constraining and Restoring iterative Algorithm for Faraday Tomography

A python 3 implementation of the CRAFT technique described in Cooray et al. 2020. The techniques takes in an observed complex linear polarization spectrum that is limited in frequency to produce a reconstructed spectrum. If you make use of this code, please cite the above mentioned paper.

Installation

Install using pip:

pip install git+https://github.com/suchethac/craft

Or, clone this directory and install locally:

git clone https://github.com/suchethac/craft
cd craft/
pip install .
# - OR -
python setup.py install

Usage

Use as a module by import craft.

For learning how to use this code, I have uploaded a demo python notebook. Additional documentation will be available in due time.

If you have any questions, please contact Suchetha Cooray at cooray{at}nagoya-u.jp
