Resumen:
We describe a method to determine the energy scale of the fluorescence detection of air-showers based on the universal shape of longitudinalshower profiles. For this purpose, the ratio of scattered Cherenkov and fluorescence light is adopted as a free parameter while fitting the individual profiles of the longitudinal deposit of the energy to the universal shape. We demonstrate the validity of the method using a Monte Carlo study based on the detector simulation of the Pierre Auger Observatory and estimate systematic uncertainties due to the choice of high energy interaction model and atmospheric conditions.
