They vary from a minimum of 6.6e-7 erg cm^-2 to a maximum of\n1.7e-6 erg cm^-2, assuming a single power law spectrum with photon index\n1.4.\nThe AGILE-MCAL instrument is a CsI calorimeter with a 4PI FoV, sensitive in\nthe energy range 0.4 - 100 MeV. Additional analysis of AGILE data is in\nprogress.",
