slitronomy 0.3.2

Sparse Linear Inversion Technique for lenstronomy

Updated and improved version of the Sparse Lens Inversion Technique (SLIT), developed within the framework of lens modelling software lenstronomy.

The documentation is available on readthedocs.org (currently in development).

IMPORTANT : the current (beta) version of SLItronomy only works with the branch dev_slit-bis on this fork of lenstronomy. In some rare cases (e.g. travis-ci builds) you may have issues with the latest stable release of PySAP. If this is the case, please use this fork of pySAP switched to branch dev-aym, instead.

Installation

This package is available through PyPi.

$ pip install slitronomy
