28 | ||
29 | The AliTPCCalibPulser class is used to get calibration data concerning the FEE using | |
30 | runs performed with the calibration pulser. | |
31 | ||
32 | The information retrieved is | |
33 | - Time0 differences | |
34 | - Signal width differences | |
35 | - Amplification variations | |
36 | ||
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. | |
39 | ||
40 | Histograms: | |
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. | |
44 | ||
45 | ||
46 | Working principle: | |
47 | ------------------ | |
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. | |
50 | ||
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 | |
55 | stored in fPadSignal. | |
56 | ||
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 ) | |
63 | ||
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) | |
68 | ||
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)), | |
71 | ||
72 | At the end of each event the EndEvent() function is called | |
73 | ||
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. | |
77 | ||
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 | |
84 | fCalRocArrayQ; | |
85 | ||
86 | ||
87 | ||
88 | User interface for filling data: | |
89 | -------------------------------- | |
90 | ||
91 | To Fill information one of the following functions can be used: | |
92 | ||
93 | Bool_t ProcessEvent(eventHeaderStruct *event); | |
94 | - process Date event | |
95 | - use AliTPCRawReaderDate and call ProcessEvent(AliRawReader *rawReader) | |
96 | ||
97 | Bool_t ProcessEvent(AliRawReader *rawReader); | |
98 | - process AliRawReader event | |
99 | - use AliTPCRawStream to loop over data and call ProcessEvent(AliTPCRawStream *rawStream) | |
100 | ||
101 | Bool_t ProcessEvent(AliTPCRawStream *rawStream); | |
102 | - process event from AliTPCRawStream | |
103 | - call Update function for signal filling | |
104 | ||
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 | |
109 | ||
110 | It is also possible to merge two independently taken calibrations using the function | |
111 | ||
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! | |
116 | ||
117 | ||
118 | ||
119 | -- example: filling data using root raw data: | |
120 | void fillSignal(Char_t *filename) | |
121 | { | |
122 | rawReader = new AliRawReaderRoot(fileName); | |
123 | if ( !rawReader ) return; | |
124 | AliTPCCalibPulser *calib = new AliTPCCalibPulser; | |
125 | while (rawReader->NextEvent()){ | |
126 | calib->ProcessEvent(rawReader); | |
127 | } | |
128 | calib->Analyse(); | |
129 | calib->DumpToFile("SignalData.root"); | |
130 | delete rawReader; | |
131 | delete calib; | |
132 | } | |
133 | ||
134 | ||
135 | What kind of information is stored and how to retrieve them: | |
136 | ------------------------------------------------------------ | |
137 | ||
138 | - Accessing the 'Reference Histograms' (Time0, signal width and Q sum information pad by pad): | |
139 | ||
140 | TH2F *GetHistoT0(Int_t sector); | |
141 | TH2F *GetHistoRMS(Int_t sector); | |
142 | TH2F *GetHistoQ(Int_t sector); | |
143 | ||
144 | - Accessing the calibration storage objects: | |
145 | ||
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 | |
149 | ||
150 | example for visualisation: | |
151 | if the file "SignalData.root" was created using the above example one could do the following: | |
152 | ||
153 | TFile fileSignal("SignalData.root") | |
154 | AliTPCCalibPulser *sig = (AliTPCCalibPulser*)fileSignal->Get("AliTPCCalibPulser"); | |
155 | sig->GetCalRocT0(0)->Draw("colz"); | |
156 | sig->GetCalRocRMS(0)->Draw("colz"); | |
157 | ||
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 | |
