Abstract
The water Cherenkov detector array (WCDA), sub-array of Large High Altitude Air Shower Observatory (LHAASO), is highly sensitive to VHE gamma-ray and is dedicated to surveying the northern sky (100GeV to 30TeV). Monitoring detector performance by observing the Crab Nebula as a standard candle and analyzing one and half a year of full array data from March 2021 to June 2022. The equal zenith Angle method was used for data processing .The saliency of crab/moon and the angular resolution of wcad are analyzed.Besides, moon shadow detection is also performed and the result is reported.
