The infill array within the Pierre Auger Observatory, first proposed and carried out by AMIGA (?Auger Muons and Infill for the Ground Array?) has grown in size and statistics. In this note we present a reconstruction suitable for infill array using the Auger Offline Software. Using real data we establish important lateral distribution function (LDF) parameters as the Ropt and , for differents LDFs: Nishimura Kamata Greisen (NKG) and power law (PL). We then obtain the CIC attenuation curve and the correlation between hybrid FD events reconstructed fromCoihueco and the S38 (450). Using this reconstruction we evaluate the angular resolution, as a function of the number of stations, zenith angle and primary energy.
