Moon shadow analysis

step 1: Event. Selection Øfrom the event loop, fill the event information into the raw histograms --- Trace the moon position, define the source and background windows. --- Confirm which window the events belong to, count the on-source and background events. --- Store the on-source and background data in histographies. LHRec. Event Tree/Ntuple Rec. Event Ntuple. Input. Svc Event. Selection Physics. Constant Hist Coord. Trans. Svc

Event Selection

step 2: Moon. Shadow Øusing the raw histograms, calculate the final moon significance histogram --- Read histography from Event. Selection, calculate the significance of moon shadow according to the Li-Ma formula. --- Store the significance in Histographies. Histography From Event. Selection Moon. Shadow Histography

step 3: Hist. Drawing （common code) Ødrawing the histograms using the LHAASO style drawing tool --- read in the root file contains the significance histogram --- the algorithm draw the histogram with LHAASO style.
