The energy scale of the Pierre Auger
Observatory is derived from fluorescence observations of extensive air showers, an intrinsically
calorimetric technique. Taking advantage of more precise measurements
of the fluorescence yield, of a deeper
understanding of the detector and consequently improved event
reconstruction and of a better estimate of the invisible energy, we present an update of the method
used to determine the energy scale.
Differences in energy with respect to
earlier measurements and the systematic uncertainties associated with
the new energy scale are discussed.
