-``PAHFIT`` is a decomposition model and tool for astronomical infrared spectra, focusing on dust and gas emission features from the interstellar medium (see `Smith, J.D.T., Draine B.T., et al., 2007, ApJ, 656, 770 <http://tir.astro.utoledo.edu/jdsmith/research/pahfit.php>`_).

 This package provides an updated python implementation of ``PAHFIT``.  While the original versions of ``PAHFIT`` (``v1.x``) were written in IDL and focused mainly on Spitzer/IRS spectroscopic observations, the newer python-based versions (``>=v2.0``) will expand instrument coverage to other existing (e.g., AKARI) and planned (e.g., JWST) facilities, and will offer a more flexible modeling framework suitable for modeling a wider range of astrophysical sources.
