64 | /// \class AliMUONDigitizerV3 | |
65 | /// | |
66 | /// The digitizer is performing the transformation to go from SDigits (digits | |
67 | /// w/o any electronic noise) to Digits (w/ electronic noise, and decalibration) | |
68 | /// | |
69 | /// The decalibration is performed by doing the reverse operation of the | |
70 | /// calibration, that is we do (Signal+pedestal)/gain -> ADC | |
71 | /// | |
72 | /// Note also that the digitizer takes care of merging sdigits that belongs | |
73 | /// to the same pad, either because we're merging several input sdigit files | |
74 | /// or with a single file because the sdigitizer does not merge sdigits itself | |
75 | /// (for performance reason mainly, and because anyway we know we have to do it | |
76 | /// here, at the digitization level). | |
77 | /// | |
78 | /// August 2011. In order to remove the need for specific MC OCDB storages, | |
79 | /// we're introducing a dependence of simulation on AliMUONRecoParam (stored | |
80 | /// in MUON/Calib/RecoParam in OCDB), which is normally (or conceptually, if | |
81 | /// you will) only a reconstruction object. That's not a pretty solution, but, | |
82 | /// well, we have to do it... | |
83 | /// This dependence comes from the fact that we must know how to decalibrate | |
84 | /// the digits, so that the decalibration (done here) - calibration (done during | |
85 | /// reco) process is (as much as possible) neutral. | |
