Resumen:
(presentación oral) In this talk we present the problems that the Delta parameter has when applying the new benchmark to the FADC traces. To work around this problem, we present a Delta_E parameter, calculated in an event by event basis. We show it is correlated with Xmax, and thus allows us to calculate an elongation rate. We also study the fluctuations, estimating the contribution to them of the detector response. Since the latter is smaller than the total fluctuation, this suggest that the fluctuation may also be sensitive to composition.
