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

Function documentation
ApplyResponseToTrackerDigit(AliMUONVDigit& digit, Bool_t addNoise)
For tracking digits, starting from an ideal digit's charge, we :
- "divide" by a gain (thus decalibrating the digit)
- add a pedestal (thus decalibrating the digit)
- add some electronics noise (thus leading to a realistic adc), if requested to do so
- sets the signal to zero if below 3*sigma of the noise
ApplyResponseToTriggerDigit(AliMUONVDigit& digit)
For trigger digits, starting from an ideal digit, we : - apply efficiency (on demand) - apply trigger masks
ApplyResponse(const AliMUONVDigitStore& store, AliMUONVDigitStore& filteredStore)
Loop over all chamber digits, and apply the response to them Note that this method may remove digits.
DecalibrateTrackerDigit(const AliMUONVCalibParam& pedestals, const AliMUONVCalibParam* gains, Int_t channel, Float_t charge, Bool_t addNoise = kFALSE, Bool_t noiseOnly = kFALSE, const TString& calibrationMode = "NOGAIN")
Decalibrate (i.e. go from charge to adc) a tracker digit, given its pedestal and gain parameters. Must insure before calling that channel is valid (i.e. between 0 and pedestals or gains->GetSize()-1, but also corresponding to a valid channel otherwise results are not predictible...) This method is completely tied to what happens in its sister method : AliMUONDigitCalibrator::CalibrateDigit, which is doing the reverse work...
Digitize(Option_t* opt = "")
Main method. We first loop over input files, and merge the sdigits we found there. Second, we digitize all the resulting sdigits Then we generate noise-only digits (for tracker only) And we finally generate the trigger outputs.
GenerateNoisyDigits(AliMUONVDigitStore& digitStore)
According to a given probability, generate digits that
have a signal above the noise cut (ped+n*sigma_ped), i.e. digits
that are "only noise".
GenerateNoisyDigitsForOneCathode(AliMUONVDigitStore& digitStore, Int_t detElemId, Int_t cathode)
Generate noise-only digits for one cathode of one detection element. Called by GenerateNoisyDigits()
GenerateNoisyDigitsForTrigger(AliMUONVDigitStore& digitStore)
Generate noise-only digits for one cathode of one detection element. Called by GenerateNoisyDigits()
Init()
Initialization of the digitization : a) create the calibrationData, according to run number b) create the trigger processing task
Int_t GetArrayIndex(Int_t cathode, Int_t trigCh, Int_t localCircuit)
Get index of array with trigger status map or efficiency
MergeWithSDigits(AliMUONVDigitStore*& digitStore, const AliMUONVDigitStore& input, Int_t mask)
Merge the sdigits in inputData with the digits already present in outputData
void SetCalibrationData(AliMUONCalibrationData* calibrationData, AliMUONRecoParam* recoParam)
AliMUONDigitizerV3(AliDigitizationInput* digInput = 0, Int_t generateNoisyDigits = 1)
void SetNSigmas(Double_t nsigmas = 4.0)
Set the number of sigmas for pedestal cut
{ fgNSigmas = nsigmas; }void BuildTriggerStatusMap()
