Dépendance en énergie à partir de cartes d'exposition La fonction Exposure FRONT,BACK (E, l, b, T 11 ) calcule l'exposition pour une énergie et une position données Ce calcul se base sur un ensemble de 36 (18 pour FRONT et 18 pour BACK) cartes d'exposition, au format root, couvrant l'intégralité du ciel à différentes énergies pour une durée d'intégration de 11 mois. Ces cartes, obtenues avec l'outil gtexpcube des Science Tools, font intervenir des énergies équiréparties en échelle logarithmique, avec 4 cartes par décade, sur un domaine d'énergie [10 MeV -178 GeV]. Une interpolation en log(E) permet, à partir de ces différentes cartes, de calculer l'exposition à une énergie E quelconque, Ci-dessous sont représentées 4 de ces 36 cartes d'exposition du ciel, en coordonnées galactiques, à E = 31.6 MeV (haut) et E = 100 GeV (bas) pour les régions FRONT (gauche) et BACK (droite) pour une durée d
