Example gallery
===============

This gallery of examples shows a variety of relatively small snippets or
examples of tasks that can be done with the Astropy core package.
Contributions from the community are encouraged!

Longer-form tutorials (or tutorials for
`affiliated packages <http://affiliated.astropy.org>`_) belong at
http://tutorials.astropy.org (and can be submitted at
`the associated github repository <https://github.com/astropy/astropy-tutorials>`_).
