Measure Extinction¶
measure_extinction is a python package to measure extinction
due to dust absorbing photons or scattering photons out of
the line-of-sight.
Extinction applies to the case for a star seen behind a foreground
screen of dust.
This package provides the tools to measure dust extinction curves using
observations of two effectively identical stars, differing only in that one
is seen through more dust than the other.
Models of the wavelength dependence of dust extinction can be found in the dust_extinction package. More complex geometries of stars and dust include additional radiative transfer effects resulting in attenuation. Models of the wavelength dependence of dust attenuation can be found in the dust_attenuation package.
This package is developed in the astropy affiliated package template.
User Documentation¶
Reporting Issues¶
If you have found a bug in measure_extinction please report it by creating a
new issue on the measure_extinction 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, measure_extinction 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.
measure_extinction follows the same workflow and coding guidelines as
Astropy. Take a look at the astropy
developer documentation for
