29 The AliTPCCalibPulser class is used to get calibration data concerning the FEE using
30 runs performed with the calibration pulser.
32 The information retrieved is
34 - Signal width differences
35 - Amplification variations
37 the seen differences arise from the manufacturing tolerances of the PASAs and are very small within
38 one chip and somewhat large between different chips.
41 For each ROC three TH2S histos 'Reference Histograms' (ROC channel vs. [Time0, signal width, Q sum]) is created when
42 it is filled for the first time (GetHisto[T0,RMS,Q](ROC,kTRUE)). The histos are stored in the
43 TObjArrays fHistoT0Array, fHistoRMSArray and fHistoQArray.
48 Raw calibration pulser data is processed by calling one of the ProcessEvent(...) functions
49 (see below). These in the end call the Update(...) function.
51 - the Update(...) function:
52 In this function the array fPadSignal is filled with the adc signals between the specified range
53 fFirstTimeBin and fLastTimeBin for the current pad.
54 before going to the next pad the ProcessPad() function is called, which analyses the data for one pad
57 - the ProcessPad() function:
58 Find Pedestal and Noise information
59 - use database information which has to be set by calling
60 SetPedestalDatabase(AliTPCCalPad *pedestalTPC, AliTPCCalPad *padNoiseTPC)
61 - if no information from the pedestal data base
62 is available the informaion is calculated on the fly ( see FindPedestal() function )
64 Find the Pulser signal information
65 - calculate mean = T0, RMS = signal width and Q sum in a range of -2+7 timebins around Q max
66 the Q sum is scaled by pad area
67 (see FindPulserSignal(...) function)
69 Fill a temprary array for the T0 information (GetPadTimesEvent(fCurrentSector,kTRUE)) (why see below)
70 Fill the Q sum and RMS values in the histograms (GetHisto[RMS,Q](ROC,kTRUE)),
72 At the end of each event the EndEvent() function is called
74 - the EndEvent() function:
75 calculate the mean T0 for each ROC and fill the Time0 histogram with Time0-<Time0 for ROC>
76 This is done to overcome syncronisation problems between the trigger and the fec clock.
78 After accumulating the desired statistics the Analyse() function has to be called.
79 - the Analyse() function
80 Whithin this function the mean values of T0, RMS, Q are calculated for each pad, using
81 the AliMathBase::GetCOG(...) function, and the calibration
82 storage classes (AliTPCCalROC) are filled for each ROC.
83 The calibration information is stored in the TObjArrays fCalRocArrayT0, fCalRocArrayRMS and
88 User interface for filling data:
89 --------------------------------
91 To Fill information one of the following functions can be used:
93 Bool_t ProcessEvent(eventHeaderStruct *event);
95 - use AliTPCRawReaderDate and call ProcessEvent(AliRawReader *rawReader)
97 Bool_t ProcessEvent(AliRawReader *rawReader);
98 - process AliRawReader event
99 - use AliTPCRawStream to loop over data and call ProcessEvent(AliTPCRawStream *rawStream)
101 Bool_t ProcessEvent(AliTPCRawStream *rawStream);
102 - process event from AliTPCRawStream
103 - call Update function for signal filling
105 Int_t Update(const Int_t isector, const Int_t iRow, const Int_t
106 iPad, const Int_t iTimeBin, const Float_t signal);
107 - directly fill signal information (sector, row, pad, time bin, pad)
108 to the reference histograms
110 It is also possible to merge two independently taken calibrations using the function
112 void Merge(AliTPCCalibPulser *sig)
113 - copy histograms in 'sig' if the do not exist in this instance
114 - Add histograms in 'sig' to the histograms in this instance if the allready exist
115 - After merging call Analyse again!
119 -- example: filling data using root raw data:
120 void fillSignal(Char_t *filename)
122 rawReader = new AliRawReaderRoot(fileName);
123 if ( !rawReader ) return;
124 AliTPCCalibPulser *calib = new AliTPCCalibPulser;
125 while (rawReader->NextEvent()){
126 calib->ProcessEvent(rawReader);
129 calib->DumpToFile("SignalData.root");
135 What kind of information is stored and how to retrieve them:
136 ------------------------------------------------------------
138 - Accessing the 'Reference Histograms' (Time0, signal width and Q sum information pad by pad):
140 TH2F *GetHistoT0(Int_t sector);
141 TH2F *GetHistoRMS(Int_t sector);
142 TH2F *GetHistoQ(Int_t sector);
144 - Accessing the calibration storage objects:
146 AliTPCCalROC *GetCalRocT0(Int_t sector); // for the Time0 values
147 AliTPCCalROC *GetCalRocRMS(Int_t sector); // for the signal width values
148 AliTPCCalROC *GetCalRocQ(Int_t sector); // for the Q sum values
150 example for visualisation:
151 if the file "SignalData.root" was created using the above example one could do the following:
153 TFile fileSignal("SignalData.root")
154 AliTPCCalibPulser *sig = (AliTPCCalibPulser*)fileSignal->Get("AliTPCCalibPulser");
155 sig->GetCalRocT0(0)->Draw("colz");
156 sig->GetCalRocRMS(0)->Draw("colz");
158 or use the AliTPCCalPad functionality:
159 AliTPCCalPad padT0(ped->GetCalPadT0());
160 AliTPCCalPad padSigWidth(ped->GetCalPadRMS());
161 padT0->MakeHisto2D()->Draw("colz"); //Draw A-Side Time0 Information
162 padSigWidth->MakeHisto2D()->Draw("colz"); //Draw A-Side signal width Information
