Resumen:
The Pierre Auger
Observatory is a detector for ultra-high energy cosmic rays. It consists
of a surface array to measure secondary particles at ground level and a
fluorescence detector to measure the development of air showers in the
atmosphere above the array. The ?hybrid? detection mode combines the
information from the two subsystems. We describe the determination of
the hybrid exposure for events observed by the fluorescence telescopes
in coincidence with at least one water-Cherenkov detector of the surface
array. A detailed knowledge of the time dependence of the detection
operations is crucial for an accurate evaluation of the exposure. We
discuss the relevance of monitoring data collected during operations,
such as the status of the fluorescence detector, background light and
atmospheric conditions, that are used in both simulation and
reconstruction.
