Reconstruction of the events recorded by the Pierre Auger Observatory — •Quentin Luce for the Pierre Auger collaboration — IKP - KIT, Eggenstein-Leopoldshafen, Germany

For the last fifteen years, the Surface Detector (SD) of the Pierre Auger Observatory is continuously recording, at ground level, the footprint of Extensive Air Showers (EAS) initiated by Ultra-High Energy Cosmic-Rays. Each triggered Water-Cherenkov Detectors, distant of 1500 m from each other and constituting an event, thus provides two information: the time at which the first particles of the shower hit the detector and the signal produced by all the particles going through it.

While from the timing information, the arrival direction of cosmic-rays is reconstructed, its energy is estimated, using the signal information, with the reconstruction of the lateral profile and the determination of the shower size S(1000). With the increase of the statistic and the evolution of our knowledge, this reconstruction procedure is evolving. The last developments of the algorithms: change of the shape of the lateral profile and improvement of its parametrisation, used to reconstruct the properties of the cosmic-rays and the resolution associated to them will be described in this presentation.
