lenstruction is a package to perform source reonstruction in cluster strong lensing.
For multiply-imaged source, the code correct lens model parameter locally up to order flexion to improve the source reconstruction.
The software is presented in Yang et al. 2020 https://arxiv.org/abs/2001.07719 .
The example presented in Yang et al.2020 (Figure 6-8) can be found in https://github.com/ylilan/lenstruction_notebooks .
lenstruction is built on software lenstronomy https://github.com/sibirrer/lenstronomy that is presented in
Birrer & Amara 2018 and is based on Birrer et al 2015.
