Function documentation
AliTRDdigitizer(AliDigitizationInput* digInput, const Text_t* name, const Text_t* title)
AliTRDdigitizer constructor
Bool_t Open(const Char_t* file, Int_t nEvent = 0)
Opens a ROOT-file with TRD-hits and reads in the hit-tree Connect the AliRoot file containing Geometry, Kine, and Hits
Bool_t Open(AliRunLoader *const runLoader, Int_t nEvent = 0)
Opens a ROOT-file with TRD-hits and reads in the hit-tree Connect the AliRoot file containing Geometry, Kine, and Hits
void AddSDigitsManager(AliTRDdigitsManager* manager)
Add a digits manager for s-digits to the input list.
Bool_t SortHits(Float_t** hits, Int_t* nhit)
Read all the hits and sorts them according to detector number in the output array <hits>.
Bool_t ConvertHits(Int_t det, const Float_t *const hits, Int_t nhit, AliTRDarraySignal* signals)
Converts the detectorwise sorted hits to detector signals
Bool_t Signal2ADC(Int_t det, AliTRDarraySignal* signals)
Converts the sampled electron signals to ADC values for a given chamber
Bool_t Signal2SDigits(Int_t det, AliTRDarraySignal* signals)
Converts the sampled electron signals to s-digits
Bool_t Digits2SDigits(AliTRDdigitsManager *const manDig, AliTRDdigitsManager *const manSDig)
Converts digits into s-digits. Needed for embedding into real data.
Bool_t MergeSDigits()
Merges the input s-digits:
- The amplitude of the different inputs are summed up.
- Of the track IDs from the input dictionaries only one is
kept for each input. This works for maximal 3 different merged inputs.
Bool_t CopyDictionary(Int_t det)
Copies the dictionary information from the s-digits arrays to the output arrays
Int_t Diffusion(Float_t vdrift, Double_t absdriftlength, Double_t exbvalue, Double_t& lRow, Double_t& lCol, Double_t& lTime)
Applies the diffusion smearing to the position of a single electron. Depends on absolute drift length.
