GNU Astronomy Utilities

GNU Astronomy Utilities (Gnuastro) is an official GNU package consisting of various programs and library functions for the manipulation and analysis of astronomical data. All the programs share the same basic command-line user interface for the comfort of both the users and developers. Gnuastro is written to comply fully with the GNU coding standards so it integrates finely with the GNU/Linux operating system. This also enables astronomers to expect a fully familiar experience in the source code, building, installing and command-line user interaction that they have seen in all the other GNU software that they use.

Gnuastro's main tarballs for each version are hosted on gnu.org, but each version is also archived here on Zenodo. Note that Gnuastro is released under GNU GPLv3+ (visible once the tarball is unpacked). The copyright notice on this Zenodo page corresponds to the contents of this page.
