ROOT event structure

Events are stored on disk in form of ROOT files. ROOT events are converted in Diana events during the Diana loop and converted back in ROOT file when writing on disk. These events are also suitable for interactive use in the ROOT shell. At the moment we have three types of events:

• Cuoricino: Contains all the data dumped by the Milano-DAQ system (rawdata).
• Apollo: Contains all the data dumped by the Genova-DAQ system (rawdata).
• Diana: Contains the same data of the Diana event. After the first loop of Diana on rawdata the dumped events will be of this third type, regardless they were in origin Cuoricino or Apollo events.
