标题： HERA-B Framework for Online Calibration and Alignment

摘要： 本文描述了HERA-B框架的体系结构和在线校准与对齐的实现。 在HERA-B中，所有触发级别的性能，包括在线重建，强烈依赖于使用适当的校准和对齐常数，这些常数可能在数据采集期间发生变化。 一个用于监控、重新计算并将这些常数分发给在线进程的系统已集成到数据获取和触发系统中。 显示英文摘要

摘要： This paper describes the architecture and implementation of the HERA-B framework for online calibration and alignment. At HERA-B the performance of all trigger levels, including the online reconstruction, strongly depends on using the appropriate calibration and alignment constants, which might change during data taking. A system to monitor, recompute and distribute those constants to online processes has been integrated in the data acquisition and trigger systems.
