This chapter describes calibrations data analysis methods and results and their application to the construction of GRBM LS1 and LS3 detectors In the first section we give basic notions on gamma-ray spectroscopy, in particular with inorganic scintillators, in order to introduce concepts and definitions that will be widely used in the following sections. In the second we outline generalities on X and gamma-ray spectral data managing with non dispersive detectors, introducing the basilar concept of response function.
Finally, at the end of the chapter we give a brief description of the Monte Carlo model of the experiment and of the satellite, still under refinement. The results from simulations were compared to the calibrations results.
