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

13. Astropy Affiliated Package

14. Strengths • Maintained mainly by dust extinction experts – New

    models added as they are created • Provides choice of models • Documentation – Including recommendations

15. 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)

16. Thanks
