GammaLib 1.6.0

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. So far, GammaLib supports analysis of data obtained with COMPTEL, Fermi/LAT, and Cherenkov telescopes (CTA, H.E.S.S., MAGIC, VERITAS). Except for HEASARC's cfitsio library that is used to implement the FITS interface, GammaLib does not rely on any third-party software. All functionalities are implemented natively
