Extinction Ensemble Properties

extinction_ensemble_props is a python package to make plots of the ensemble properties of extinction curves. The goal of this package is to provide a straightforward way to plot the properties of different samples of extinction curves either alone or one property versus another one. This can be helpful for investigating correlations and how difference samples vary (e.g., between different galaxies).

Extinction describes the effects of dust on observations of single star due to the dust along the line-of-sight to a star removing flux by absorbing photons and scattering photons out of the line-of-sight. The wavelength dependence of dust extinction (also know as extinction curves) provides fundamental information about the size, composition, and shape of interstellar dust grain. In general, extinction models are used to model or correct the effects of dust on observations.

The properties of dust extinction curves includes measurements of the dust (and gas) columns (e.g., A(V), R(V), N(H)/A(V)) and parameters that describe the shape of the extinction curve (.e.g, FM90 parameters [C1, C2, B3, …]).

Reporting Issues

If you have found a bug in extinction_ensemble_props please report it by creating a new issue on the extinction_ensemble_props GitHub issue tracker.

Please include an example that demonstrates the issue sufficiently so that the developers can reproduce and fix the problem. You may also be asked to provide information about your operating system and a full Python stack trace. The developers will walk you through obtaining a stack trace if it is necessary.

Contributing

Like the Astropy project, extinction_ensemble_props 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.
