3. DAMPE Software? Database – all needed Simulation – MC simulation. Output data format same as detector (Raw Data) – output into Database/Simulation Calibration – input Raw Data – output many calibration results into Database/Calibration Reconstruction – input Raw Data and Calibration results – some levels of temporary data, and distribution data for analysis user – output into Database/DataLevel_X/ Or Database/Distribution – Event format ？？ Visualization – input distribution data / use geometry parameter in database Analysis software – input distribution data for analysis 3
