21 | /// This is the base class of a MUON digit that most client code should deal with. | |
22 | /// There should be no reason to have to use a concrete class in most cases. | |
23 | /// | |
24 | /// All digits have basic features, like : | |
25 | /// | |
26 | /// - a way to identify it : detection element, electronics card and | |
27 | /// channel, cathode. Note that some static methods exists to compact | |
28 | /// those 4 informations into a single 4 bytes integer (stored in the | |
29 | /// fUniqueID data member present in all TObjects). | |
30 | /// | |
31 | /// - its charge | |
32 | /// | |
33 | /// - a set of boolean methods to indicate whether the digit has been calibrated, etc... | |
34 | /// | |
35 | /// In addition, if HasMCInformation is true, the digit store also the list | |
36 | /// of MC tracks that contributed to its charge | |
37 | /// | |
38 | /// Also, if HasGeometryInformation is true, the digit knows the position and | |
39 | /// the (half) dimensions (in cm) of the pad it corresponds to. | |
