Description
In addition to the standard $X_\mathrm{max}$ and energy, the longitudinal profiles of extensive air showers contain some more interesting information. For energies above $10^{17.8}$ eV, we present the average profiles as a function of depth measured for the first time at the Pierre Auger Observatory. The profile shapes for different energy ranges are all well reproduced by a Gaisser-Hillas function with two parameters. A detailed analysis of the systematic uncertainties is done using data and a full detector simulation, and the results are compared with predictions of hadronic interaction models for different primaries.
