论文摘要
探测器表征和数据质量 - 简而言之，“ DETCHAR” - 活动是优化数据摄入期（“运行”）并将重力波（GW）候选者转变为已确认事件的关键。 Ligo和处女座Detchar组从检测器到最终分析都活跃，并涵盖各种延迟：首先在线标记搜索管道可以实时分析的数据；然后，针对广泛的天文学家社区以进行后续观察的快速审查（最多几十分钟）的公开公开警报；最后，离线工作以定义最终数据集以及将公开发布和发布的GW事件的最终列表。 这些程序总结了O3跑步期间的Ligo -Virgo Detchar性能（2019年4月至2020年3月），并描述了应该在2022年夏季开始的O4运行的主要改进和升级，并包括第四探测器：Kagra。
Detector characterization and data quality -- in short "DetChar" -- activities are key to optimize the performance of data-taking periods ("runs") and to turn gravitational-wave (GW) candidates into confirmed events. The LIGO and Virgo DetChar groups are active from the detector to the final analysis and cover various latencies: online first, to tag the data that search pipelines can analyze in real-time; then, the quick vetting (few tens of minutes at most) of the open public alerts targeting the broad astronomer community for follow-up observations; finally, offline work to define the final datasets and the final lists of GW events to be published and released publicly. These proceedings summarize the LIGO-Virgo DetChar performance during the O3 run (April 2019 - March 2020) and describe the main improvements and upgrades that are foreseen for the O4 run that should start during Summer 2022 and include a fourth detector: KAGRA.
