Reconstruction of events recorded with the surface detector of the Pierre Auger Observatory Aab, A. Bueno Villar, Antonio Data processing Large detector systems for particle and astroparticle physics Large detector-systems performance Performance of High Energy Physics Detectors Cosmic rays arriving at Earth collide with the upper parts of the atmosphere, thereby inducing extensive air showers. When secondary particles from the cascade arrive at the ground, they are measured by surface detector arrays. We describe the methods applied to the measurements of the surface detector of the Pierre Auger Observatory to reconstruct events with zenith angles less than 60 using the timing and signal information recorded using the water-Cherenkov detector stations. In addition, we assess the accuracy of these methods in reconstructing the arrival directions of the primary cosmic ray particles and the sizes of the induced showers. 2021-02-19T09:55:53Z 2021-02-19T09:55:53Z 2020-10 journal article Aab, A., Abreu, P., Aglietta, M., Albury, J.
