LHAASO实验的第一个水切伦科夫探测器（WCDA-1）自2019年4月以来一直在运行。第一年的数据已经通过观察蟹状星云作为标准蜡烛进行了分析，以测试其性能。WCDA-1实现了每年65 mCU的灵敏度，统计阈值为5
The first Water Cherenkov detector of the LHAASO experiment (WCDA-1) has been operating since April 2019. The data for the first year have been analyzed to test its performance by observing the Crab Nebula as a standard candle. The WCDA-1 achieves a sensitivity of 65 mCU per year, with a statistical threshold of 5
