GammaLib

GammaLib is a versatile toolbox for the scientific analysis of astronomical gamma-ray data. It consists of a C++ library and a Python module that exposes the full functionality of the library to Python. The library provides an abstract data analysis framework that is independent of any specific gamma-ray telescope. Instrument specific aspects, such as handling of data formats and response functions, are implemented as isolated and well defined modules sharing an identical abstract interface. This enables a joint multi-instrument analysis of data, allowing for consistent broad-band spectral fitting or imaging. GammaLib supports so far the analysis of data obtained with CGRO/COMPTEL, Fermi/LAT, INTEGRAL/SPI and Cherenkov telescopes (CTA, H.E.S.S., MAGIC, VERITAS).

GammaLib does not rely on any third-party software with the exception of HEASARC's cfitsio library that is the basis of the FITS file interface. All other functionalities are implemented natively.

GammaLib is developed by a community of enthousiastic gamma-ray astronomers with support from engineers. The lead institute is
