pyZELDA
Introduction
This repository provides analysis code for Zernike wavefront sensors in high-contrast imaging applications. ZELDA stands for Zernike sensor for Extremely Low-level Differential Aberration (N'Diaye et al. 2013). It is also the name of the Zernike wavefront sensor implemented in the VLT/SPHERE (Beuzit et al. 2019) instrument.
The formalism of the Zernike wavefront sensor and the demonstration of its capabilities in the VLT/SPHERE instrument are presented in the following papers:

N'Diaye, Vigan, Dohlen et al., 2016, A&A, 592, A79
Vigan, N'Diaye, Dohlen et al., 2019, A&A, 629, A11

Requirements
The package relies on usual packages for data science and astronomy: numpy, scipy, matplotlib and astropy.
Installation
The easiest is to install pyzelda using pip:
pip install pyzelda

Otherwise your can download the current repository and install the package manually:
cd pyZELDA-master/
python setup.py install
