SMILI: Sparse Modeling Imaging Library for Interferometry

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).

Documentation and Contact

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and dynamically developed for many new topics and challenges of the EHT, the documentation is not perfect and sometimes outdated due to dynamical changes in the data structure.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 NRAO / MIT Haystack Observatory if you have any questions about this library. You may contact with following other core developers, too.

  • Kazu Akiyama at NRAO / MIT Haystack Observatory, the Main Developer
  • Fumie Tazaki at National Astronomical Observatory of Japan
  • Shiro Ikeda at the Institute of Statistical Mathematics
  • Kotaro Moriyama at National Astronomical Observatory of Japan

How to install this library?

Please have a look at the installation guide.

What's the reference for this software?

We are now preparing a software paper (Akiyama et al. in prep.) 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.

There are some other related publications about imaging techniques developed with, or implemented in SMILI or its earlier version.

License

SMILI is licensed under GPLv3 as described in LICENSE.txt. SMILI also includes an internal package from other libraries (LBFGSB), or which corresponding LICENSE files are included.
