dust_extinction python package

Briefly presents the astropy affiliated dust_extinction python package. Package currently provides ultraviolet through near-infrared models of extinction curves for use in forward modeling and/or correcting for the effects of interstellar extinction on observations of stars.

  2. Motivations • Provide up-to-date dust extinction models – Forward modeling

    and correcting observations • So I can learn open development skills • Contribute to the pyastro community • Have all the models available for my papers • Package – for those that like dust – for those that just want it to go away
  3. Strengths • Maintained mainly by dust extinction experts – New

    models added as they are created • Provides choice of models • Documentation – Including recommendations
  4. Future/Needs • Needs review by general users – Maintained by

    experts • Add more models – Currently covers UV – NIR – Add dust grain models (X-ray to mm) – Add MIR models • What else needed? (issues very welcome)
