AstroLib is a growing set of astronomical utility libraries for Python. We hope it will fulfill a similar role to the ASTRON library for IDL in future, providing the core tools needed for astronomical Python applications. The developers are an informal group of collaborators from several institutions, led by STScI. Active Python coders are welcome to contribute to our effort (see below). You can find the repository and its Trac site here:



End user documentation (from Sphinx) will be posted on in the near future. This wiki page is for contributors to document ideas about functionality, structure and standards for AstroLib. Related discussion occurs on the Astropy mailing list. We are happy to receive community feedback on our plans and development as they progress.

Our effort naturally tends to be focused on capabilities that are important for our own projects, but we want to keep the code useful for others and set a framework that allows you to build on what we provide. Those with good ideas and time to contribute will find that the lead developer team does not expect a monopoly on defining how things are done (with the exception that authors are strongly encouraged to meet some documentation and testing standards). Nevertheless, we would like to maintain some overall coherence and self-consistency within AstroLib, through ongoing negotiation between authors.

For reference; here is the link to the documentation for the IDL "ASTRON library":
