Codes

In the course of our research we have written a number of scientific codes and software packages. In the spirit of reproducible research we make these codes publicly available.

Most codes are now hosted on the astro-informatics Github pages.

If you use any of the codes in work that results in publication we kindly request that you reference the appropriate code webpage and papers. Thanks and we hope you find these codes useful!
