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.
