Abstract
The Pierre Auger Observatory is the largest extensive air-shower (EAS) experiment in the world. The aim of the experiment is to determine the energy, composition and origin of the UHE cosmic-rays above 1Â EeV using two complementary detection techniques: a ground array of water Cherenkov tanks and fluorescence detectors (FD). The FDs are fully operational since February 2007. First physics results have been presented in 2005. The FD plays a major role not only in the calibration of the energy scale of the experiment, but also in the understanding of the systematics of the whole experiment using the data themselves. This presentation focuses on the data taken by the 24 fluorescence telescopes. A summary of the current status and overview of the FD will be given. The reconstruction performance based on real data and Monte Carlo will be discussed. A summary on the systematics and preliminary results based on FD data are also presented.
