+ <h4>The AliTPCCalibCE class is used to get calibration data from the Central Electrode
+ using laser runs.</h4>
+
+ The information retrieved is
+ <ul style="list-style-type: square;">
+ <li>Time arrival from the CE</li>
+ <li>Signal width</li>
+ <li>Signal sum</li>

+
+ <h3><a name="working">I. Working principle</a></h3>
+
+ <h4>Raw laser data is processed by calling one of the ProcessEvent(...) functions
+ (see below). These in the end call the Update(...) function.</h4>
+
+ <ul style="list-style-type: square;">
+ <li>the Update(...) function:<br />
+ In this function the array fPadSignal is filled with the adc signals between the specified range
+ fFirstTimeBin and fLastTimeBin for the current pad.
+ before going to the next pad the ProcessPad() function is called, which analyses the data for one pad
+ stored in fPadSignal.
+ </li>
+ <ul style="list-style-type: square;">
+ <li>the ProcessPad() function:</li>
+ <ol style="list-style-type: decimal;">
+ <li>Find Pedestal and Noise information</li>
+ <ul style="list-style-type: square;">
+ <li>use database information which has to be set by calling<br />
+ SetPedestalDatabase(AliTPCCalPad *pedestalTPC, AliTPCCalPad *padNoiseTPC)</li>
+ <li>if no information from the pedestal data base
+ is available the informaion is calculated on the fly
+ ( see FindPedestal() function )</li>
+ </ul>
+ <li>Find local maxima of the pad signal</li>
+ <ul style="list-style-type: square;">
+ <li>maxima arise from the laser tracks, the CE and also periodic postpeaks after the CE signal have
+ have been observed ( see FindLocalMaxima(...) )</li>
+ </ul>
+ <li>Find the CE signal information</li>
+ <ul style="list-style-type: square;">
+ <li>to find the position of the CE signal the Tmean information from the previos event is used
+ as the CE signal the local maximum closest to this Tmean is identified</li>
+ <li>calculate mean = T0, RMS = signal width and Q sum in a range of -4+7 timebins around Q max position
+ the Q sum is scaled by pad area (see FindPulserSignal(...) function)</li>
+ </ul>
+ <li>Fill a temprary array for the T0 information (GetPadTimesEvent(fCurrentSector,kTRUE)) (why see below)</li>
+ <li>Fill the Q sum and RMS values in the histograms (GetHisto[RMS,Q](ROC,kTRUE))</li>
+ </ol>
+ </ul>
+ </ul>
+
+ <h4>At the end of each event the EndEvent() function is called</h4>
+
+ <ul style="list-style-type: square;">
+ <li>the EndEvent() function:</li>
+ <ul style="list-style-type: square;">
+ <li>calculate the mean T0 for side A and side C. Fill T0 histogram with Time0-<Time0 for side[A,C]>
+ This is done to overcome syncronisation problems between the trigger and the fec clock.</li>
+ <li>calculate Mean T for each ROC using the COG aroud the median of the LocalMaxima distribution in one sector</li>
+ <li>calculate Mean Q</li>
+ <li>calculate Global fit parameters for Pol1 and Pol2 fits</li>
+ </ul>
+ </ul>
+
+ <h4>After accumulating the desired statistics the Analyse() function has to be called.</h4>
+ <ul style="list-style-type: square;">
+ <li>the Analyse() function:</li>
+ <ul style="list-style-type: square;">
+ <li>calculate the mean values of T0, RMS, Q for each pad, using
+ the AliMathBase::GetCOG(...) function</li>
+ <li>fill the calibration storage classes (AliTPCCalROC) for each ROC</li>
+ (The calibration information is stored in the TObjArrays fCalRocArrayT0, fCalRocArrayRMS and fCalRocArrayQ</li>
+ </ul>
+ </ul>
+
+ <h3><a name="user">II. User interface for filling data</a></h3>
+
+ <h4>To Fill information one of the following functions can be used:</h4>
+
+ <ul style="list-style-type: none;">
+ <li> Bool_t ProcessEvent(eventHeaderStruct *event);</li>
+ <ul style="list-style-type: square;">
+ <li>process Date event</li>
+ <li>use AliTPCRawReaderDate and call ProcessEvent(AliRawReader *rawReader)</li>
+ </ul>
+ <br />
+
+ <li> Bool_t ProcessEvent(AliRawReader *rawReader);</li>
+ <ul style="list-style-type: square;">
+ <li>process AliRawReader event</li>
+ <li>use AliTPCRawStream to loop over data and call ProcessEvent(AliTPCRawStream *rawStream)</li>
+ </ul>
+ <br />
+
+ <li> Bool_t ProcessEvent(AliTPCRawStream *rawStream);</li>
+ <ul style="list-style-type: square;">
+ <li>process event from AliTPCRawStream</li>
+ <li>call Update function for signal filling</li>
+ </ul>
+ <br />
+
+ <li> Int_t Update(const Int_t isector, const Int_t iRow, const Int_t
+ iPad, const Int_t iTimeBin, const Float_t signal);</li>
+ <ul style="list-style-type: square;">
+ <li>directly fill signal information (sector, row, pad, time bin, pad)
+ to the reference histograms</li>
+ </ul>
+ </ul>
+
+ <h4>It is also possible to merge two independently taken calibrations using the function</h4>
+
+ <ul style="list-style-type: none;">
+ <li> void Merge(AliTPCCalibSignal *sig)</li>
+ <ul style="list-style-type: square;">
+ <li>copy histograms in 'sig' if they do not exist in this instance</li>
+ <li>Add histograms in 'sig' to the histograms in this instance if the allready exist</li>
+ <li>After merging call Analyse again!</li>
+ </ul>
+ </ul>
+
+
+ <h4>example: filling data using root raw data:</h4>
+ <pre>
+ void fillCE(Char_t *filename)
+ {
+ rawReader = new AliRawReaderRoot(fileName);
+ if ( !rawReader ) return;
+ AliTPCCalibCE *calib = new AliTPCCalibCE;
+ while (rawReader->NextEvent()){
+ calib->ProcessEvent(rawReader);
+ }
+ calib->Analyse();
+ calib->DumpToFile("CEData.root");
+ delete rawReader;
+ delete calib;
+ }
+ </pre>

+ <h3><a name="info">III. What kind of information is stored and how to retrieve it</a></h4>
+
+ <h4><a name="info:stored">III.1 Stored information</a></h4>
+ <ul style="list-style-type: none;">
+ <li>Histograms:</li>
+ <ul style="list-style-type: none;">
+ <li>For each ROC three TH2S histos 'Reference Histograms' (ROC channel vs. [Time0, signal width, Q sum])
+ is created when it is filled for the first time (GetHisto[T0,RMS,Q](ROC,kTRUE)). The histos are
+ stored in the TObjArrays fHistoT0Array, fHistoRMSArray and fHistoQArray.</li>
+ </ul>
+ <br />
+
+ <li>Calibration Data:</li>
+ <ul style="list-style-type: none;">
+ <li>For each ROC three types of calibration data (AliTPCCalROC) is stored: for the mean arrival Time,
+ the signal width and the signal Sum. The AliTPCCalROC objects are stored in the TObjArrays
+ fCalRocArrayT0, fCalRocArrayRMS , fCalRocArrayQ. The object for each roc is created the first time it
+ is accessed (GetCalRoc[T0,RMS,Q](ROC,kTRUE));</li>
+ </ul>
+ <br />
+
+ <li>For each event the following information is stored:</li>
+
+ <ul style="list-style-type: square;">
+ <li>event time ( TVectorD fVEventTime )</li>
+ <li>event id ( TVectorD fVEventNumber )</li>
+ <br />
+ <li>mean arrival time for each ROC ( TObjArray fTMeanArrayEvent )</li>
+ <li>mean Q for each ROC ( TObjArray fQMeanArrayEvent )</li>
+ <li>parameters of a plane fit for each ROC ( TObjArray fParamArrayEventPol1 )</li>
+ <li>parameters of a 2D parabola fit for each ROC ( TObjArray fParamArrayEventPol2 )</li>
+ </ul>
+ </ul>
+
+ <h4><a name="info:retrieve">III.2 Retrieving information</a></h4>
+ <ul style="list-style-type: none;">
+ <li>Accessing the 'Reference Histograms' (Time0, signal width and Q sum information pad by pad):</li>

+ <li>TH2F *GetHistoT0(Int_t sector);</li>
+ <li>TH2F *GetHistoRMS(Int_t sector);</li>
+ <li>TH2F *GetHistoQ(Int_t sector);</li>
+ </ul>
+ <br />
+
+ <li>Accessing the calibration storage objects:</li>
+ <ul style="list-style-type: square;">
+ <li>AliTPCCalROC *GetCalRocT0(Int_t sector); // for the Time0 values</li>
+ <li>AliTPCCalROC *GetCalRocRMS(Int_t sector); // for the signal width values</li>

+ </ul>
+ <br />
+
+ <li>Accessin the event by event information:</li>
+ <ul style="list-style-type: square;">
+ <li>The event by event information can be displayed using the</li>
+ <li>MakeGraphTimeCE(Int_t sector, Int_t xVariable, Int_t fitType, Int_t fitParameter)</li>

+
+ <h4>example for visualisation:</h4>
+ <pre>
+ //if the file "CEData.root" was created using the above example one could do the following:

+ AliTPCCalibCE *ce = (AliTPCCalibCE*)fileCE->Get("AliTPCCalibCE");
+ ce->GetCalRocT0(0)->Draw("colz");

+ AliTPCCalPad padSigWidth(ped->GetCalPadRMS());
+ padT0->MakeHisto2D()->Draw("colz"); //Draw A-Side Time0 Information

+
+ //display event by event information:
+ //Draw mean arrival time as a function of the event time for oroc sector A00
+ ce->MakeGraphTimeCE(36, 0, 2)->Draw("alp");
