Python package for the evaluation of Zernike polynomials
This is an installable package that can be used to simulate wavefront maps as a series of Zernike polynomials of arbitrary radial order. It supports any kind of aperture mask, making it flexible for evaluating Zernikes in any astronomical pupil.
To install ZERN, you can follow these simple steps:
Download the repo directly from Github by running git clone:
git clone https://github.com/AlvaroMenduina/ZERN.git <your_local_dir>
Move to where you copied the repository files
cd <your_local_dir>
And run
python setup.py sdist
pip install .
To test whether the installation was successful, you can try to import the module
import zern.zern_core as zern
_test = zern.Zernike(mask=None)If you are interested in learning how to uze ZERN, you can find several Jupyter notebooks here
This package has been thoroughly tested to ensure the results are consistent.
