====== INTEGRAL/IBIS ======
The INTEGRAL observatory operating in a hard X-ray/gamma domain has gathered a large observational data since 2003. Most of the observing time was dedicated to the Galactic source population study, making possible the deepest Galactic survey in hard X-rays ever compiled. Sky images of the Galactic Plane (|b|<17.5 deg) obtained with the IBIS telescope have been produced in three energy bands : 17−60, 17−35, and 35−80 keV. All the surveys are based on the nine-year sky maps, and the 17−60 keV survey is also available with the fourteen-years sky maps.
All maps were originally convolved with instrumental point spread function (PSF) which is Gaussian (σ=5').
The units of the Healpix maps are ''mCrab''. \\
