It implements different tools and high-level to perform radio interferometric imaging, _i.e._ to recover images from the Fourier measurements taken by radio interferometric telescopes.
 
 **PURIFY** leverages recent developments in the field of compressive sensing and convex optimization. Low-level functionality to solve the resulting convex optimisation is factored into the open-source companion code, [**SOPT**](https://github.com/astro-informatics/sopt), also written by the authors of **PURIFY**. For further background please see the [reference](#references-and-citation) section.
