###### PAHFIT ###### ``pahfit`` is a python package providing a decomposition model for astronomical infrared spectra, focusing on dust and gas emission features from the interstellar medium. The original versions of PAHFIT (v1.x) were written in IDL and focused mainly on Spitzer/IRS spectroscopic observations. This python-based versions (>=v2.0) will provide expanded capabilities including more instrument (e.g., AKARI and JWST) and a more flexible modeling framework suitable for modeling a wider range of astrophysical sources. For details for the IDL version of PAHFIT see `Smith, J.D.T., Draine B.T., et al., 2007, ApJ, 656, 770 `_. This package is potentially an `astropy affiliated package `_ and uses the `astropy.modeling `_ framework.

Reporting Issues ================ If you have found a bug in ``pahfit`` please report it by creating a new issue on the ``pahfit`` `GitHub issue tracker `_. Please include an example that demonstrates the issue sufficiently so that the developers can reproduce and fix the problem. Contributing ============ Like the `Astropy`_ project, ``pahfit`` is made both by and for its users. We accept contributions at all levels, spanning the gamut from fixing a typo in the documentation to developing a major new feature. We welcome contributors who will abide by the `Python Software Foundation Code of Conduct `_. ``pahfit`` follows the same workflow and coding guidelines as `Astropy`_.
