SMILI is a python-interfaced library for interferometric imaging using sparse sampling techniques and other regularization methods. SMILI is mainly designed for very long baseline interferometry, and has been under the active development primarily for the Event Horizon Telescope (EHT).

Here is the SMILI documentation. Since SMILI has yet been actively and dynamically developed for many new topics and challenges of the EHT, the documentation is not perfect and sometimes outdated due to dynamical changes in the data structure.

Please contact with Kazu Akiyama at MIT Haystack Observatory if you have any questions about this library. You may contact with following other core developers, too.

• Kazu Akiyama at MIT Haystack Observatory, Primary Developer
• Kotaro Moriyama at Goethe-Universität Frankfurt am Main
• Fumie Tazaki at National Astronomical Observatory of Japan
• Ilje Cho at Instituto de Astrofísica de Andalucía
• Shiro Ikeda at the Institute of Statistical Mathematics

Please have a look at the installation guide.

We are now preparing a software paper describing the latest snapshot of some new functions after Kuramochi et al. 2018. Until this paper will come out, please cite the following two papers for SMILI.

• Akiyama et al. 2017b, AJ, 153, 159
