Query: Study of the Gamma-ray performance of the GAMMA-400 Calorimeter   GAMMA-400 is a new space mission, designed as a dual experiment, capable to
study both high energy gamma rays (from $\sim$100 MeV to few TeV) and cosmic
rays (electrons up to 20 TeV and nuclei up to $\sim$10$^{15}$ eV). The full
simulation framework of GAMMA-400 is based on the Geant4 toolkit. The details
of the gamma-ray reconstruction pipeline in the pre-shower and calorimeter will
be outlined. The performance of GAMMA-400 (PSF, effective area) have been
obtained using this framework. The most updated results on them will be shown.
