Data Handling (old) CaloBase CellProperties PRecDet of CaloDataFrames CaloDataFrame … CellProperties User needs to loop over all data frames, find the cell index inside the data frame, And match it to the index of the cell in the CaloBase. CaloHits, CaloDataFrames, & CaloRecHits all do this.

Data Handling (new) CaloBase Master Readout Allows simulation & reconstruction for regions, individual cells Associate the SlaveReadouts with MasterReadouts Use realistic DAQ configuration Slave ReadoutCaloDetUnit Slave Readout Master Readout
