astropy package contains key functionality and common tools needed for
performing astronomy and astrophysics with Python. It is at the core of the
Astropy Project, which aims to enable
the community to develop a robust ecosystem of affiliated packages
covering a broad range of needs for astronomical research, data
processing, and data analysis.
If you use Astropy for work presented in a publication or talk please help the project via proper citation or acknowledgement. This also applies to use of software or affiliated packages that depend on the astropy core package.
