Simulation Results

We have applied the Kalmaex algorithm on a set of simulated tracker events (both background particles and gamma-ray photons) obtained by the montecarlo code GAMS [Longo et al., 2002]. This showed that this technique gives a good result, the precision in direction evaluation is only 30% worst with respect to the precision of the on-ground processing. Figure 4.6 show the $68 \%$ containement radius of gamma-ray photons reconstructed with the Kalmaex algorithm as a function of energy for different angles of incidence. The strong dependence on energy is due to multiple scattering effect which affect the less energetic tracks.

Figure 4.6: 68% containement radius of photons reconstructed whith the Kalmex algorithm, for 0 and 50 degree of incidence angles.
