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) belong at https://learn.astropy.org (and can be submitted at the associated github repository).
