AKPIK 1.2: Vortrag

The operation of the next-generation gamma-ray telescopes as observatories, the wish of currently operating instruments to archive and publish their data in an accessible format, and enabling multi-instrument analyses are strong reasons for developing an open, software independent format for gamma-ray data.

A first attempt of a common specification has been developed by members of different Imaging Atmospheric Cherenkov Telescopes (IACT) within the "Data formats for gamma-ray astronomy" initiative. The current version defines formats for high-level gamma-ray data, including event lists of candidate photons and instrument response functions, serialized as FITS files.

Open-source software for gamma-ray analyses, including gammapy and ctools, have recently developed support for this format and, as a result, a series of publications relying on standardized datasets and software have been issued.

Currently, an effort to formalize the endeavor is underway, creating a Coordination Committee formed from representatives of the participating instruments to steer the future development of the specification.

In this talk, current developments and future plans will be presented, including the already implemented extension to ground-based wide-field experiments and possible extension to other messengers.
