Descripción
Mounted on the International Space Station(ISS), the Extreme Universe
Space Observatory, on-board the Japanese Experimental Module (JEM-EUSO),
relies on the well established fluorescence technique to observe
Extensive Air Showers (EAS) developing in the earth's atmosphere.
Focusing on the detection of Ultra High Energy Cosmic Rays (UHECR) in
the decade of 1020eV, JEM-EUSO will face new challenges by
applying this technique from space. The EUSO Simulation and Analysis
Framework (ESAF) has been developed in this context to provide a full
end-to-end simulation frame, and assess the overall performance of the
detector. Within ESAF, angular reconstruction can be separated into two
conceptually different steps. The first step is pattern recognition, or
filtering, of the signal to separate it from the background. The second
step is to perform different types of fitting in order to search for the
relevant geometrical parameters that best describe the previously
selected signal. In this paper, we discuss some of the techniques we
have implemented in ESAF to perform the geometrical reconstruction of
EAS seen by JEM-EUSO. We also conduct thorough tests to assess the
performances of these techniques in conditions which are relevant to the
scope of the JEM-EUSO mission. We conclude by showing the expected
angular resolution in the energy range that JEM-EUSO is expected to
observe.
