XARA: a python package for eXtreme Angular Resolution Astronomy

XARA is a python module that was initially designed to create, extract and manipulate Fourier-phase out of diffraction-dominated astronomical images, using the theory introduced by several journal papers:

• Martinache (2010), ApJ, 724, 464
• Martinache (2013), PASP, 125, 422
• Martinache et al (2020), A&A, 636, A72

Over the years, the package has been used by several graduate students, motivated by obsevring projects using a wide range of instruments (ground based adaptive optics assisted cameras as well as space borne instruments). The same students have often made their own fork of the project.

Tutorial/documentation
