Description

Gammapy analyses gamma-ray data and creates sky images, spectra and light curves, from event lists and instrument response information; it can also determine the position, morphology and spectra of gamma-ray sources. It is used to analyse data from H.E.S.S., MAGIC, VERITAS, Fermi-LAT, HAWC, and the Cherenkov Telescope Array Observatory (CTAO).

The version of the second Long Term Support version of Gammapy, LTS v2.0. The first one was LTS v1.0.
