CONCLUSIONS - The Commissioning phase has been carried out with excellent results. - The PL subsystems are in general working in a satisfactory and nominal way. In several cases, during the first year, we could improve the pre-launch performance. - During the second year, we plan to further optimize the g-rays, x-rays and MCAL functional performance. 5th Science AGILE Workshop – ESRIN, Frascati, 12-13 June 2008
