Resumen:
Themeasurement of energy is one of the most important and challengingtasks of an astroparticle observatory, especially given that theenergy must be accompanied by reliable statistical and systematicuncertainties. The energy scale of the Pierre Auger Observatory isbased on observations made by its fluorescence detector, takingadvantage of the near-calorimetric measurements afforded by thistechnique. This fluorescence energy calibration is transferred to thesurface detector measurements via coincident fluorescence and surfacedetector observations of air showers at the hybrid observatory. Inthis contribution, we present the current status of our energy scale.We demonstrate our confidence in the cosmic ray energy assignments bydiscussing our methods and their systematic and statisticaluncertainties. We describe the impact of recent improvements in theestimation of invisible energy, and discuss uncertainties associatedwith the fluorescence yield, the atmosphere, detector calibration,and the event reconstruction process.
