Fermi Gamma-ray Space Telescope

The Fermi Gamma-ray Space Telescope was launched on 11 June 2008, becoming the most sensitive gamma-ray telescope on orbit, succeeding INTEGRAL. Fermi includes two scientific instruments, the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM):
- The LAT is an imaging gamma-ray detector (a pair-conversion instrument) which detects photons with energy from 20 MeV to 300 GeV
- The GBM consists of 14 scintillation detectors covering the range ~150 keV to ~30 MeV, that can detect gamma-ray bursts in that energy range

CADE only serves data obtained with the LAT instrument, in 5 energy bands: 30-100 Mev (Band 1) at an angular resolution of 3°, 100-300 Mev (Band 2) at 2°, 300-1000 Mev (Band 3) at 1°, 1-3 Gev (Band 4) at 0.4° and 3-300 GeV (Band 5) at 0.2°. Healpix maps are in units of cnts/s/cm^2/sr.
