The program generates a list of photons and images of the galactic and extragalactic background and of the sources, in a selected energy range and in a given region of the sky.5 pages, 2 figures, proceedings of: Science with the New Generation of High Energy Gamma-ray Experiments: between Astrophysics and Astroparticle PhysicsAstrophysicstext
