32 <h4>The AliTPCCalibCE class is used to get calibration data from the Central Electrode
33 using laser runs.</h4>
35 The information retrieved is

49 <h3><a name="working">I. Working principle</a></h3>
51 <h4>Raw laser data is processed by calling one of the ProcessEvent(...) functions
52 (see below). These in the end call the Update(...) function.</h4>
54 <ul style="list-style-type: square;">
55 <li>the Update(...) function:<br />
56 In this function the array fPadSignal is filled with the adc signals between the specified range
57 fFirstTimeBin and fLastTimeBin for the current pad.
58 before going to the next pad the ProcessPad() function is called, which analyses the data for one pad
61 <ul style="list-style-type: square;">
62 <li>the ProcessPad() function:</li>
63 <ol style="list-style-type: decimal;">
64 <li>Find Pedestal and Noise information</li>
65 <ul style="list-style-type: square;">
66 <li>use database information which has to be set by calling<br />
67 SetPedestalDatabase(AliTPCCalPad *pedestalTPC, AliTPCCalPad *padNoiseTPC)</li>
68 <li>if no information from the pedestal data base
69 is available the informaion is calculated on the fly
70 ( see FindPedestal() function )</li>
72 <li>Find local maxima of the pad signal</li>
73 <ul style="list-style-type: square;">
74 <li>maxima arise from the laser tracks, the CE and also periodic postpeaks after the CE signal have
75 have been observed ( see FindLocalMaxima(...) )</li>
77 <li>Find the CE signal information</li>
78 <ul style="list-style-type: square;">
79 <li>to find the position of the CE signal the Tmean information from the previos event is used
80 as the CE signal the local maximum closest to this Tmean is identified</li>
81 <li>calculate mean = T0, RMS = signal width and Q sum in a range of -4+7 timebins around Q max position
82 the Q sum is scaled by pad area (see FindPulserSignal(...) function)</li>
84 <li>Fill a temprary array for the T0 information (GetPadTimesEvent(fCurrentSector,kTRUE)) (why see below)</li>
85 <li>Fill the Q sum and RMS values in the histograms (GetHisto[RMS,Q](ROC,kTRUE))</li>
90 <h4>At the end of each event the EndEvent() function is called</h4>
92 <ul style="list-style-type: square;">
93 <li>the EndEvent() function:</li>
94 <ul style="list-style-type: square;">
95 <li>calculate the mean T0 for side A and side C. Fill T0 histogram with Time0-<Time0 for side[A,C]>
96 This is done to overcome syncronisation problems between the trigger and the fec clock.</li>
97 <li>calculate Mean T for each ROC using the COG aroud the median of the LocalMaxima distribution in one sector</li>
98 <li>calculate Mean Q</li>
99 <li>calculate Global fit parameters for Pol1 and Pol2 fits</li>
103 <h4>After accumulating the desired statistics the Analyse() function has to be called.</h4>
104 <ul style="list-style-type: square;">
105 <li>the Analyse() function:</li>
106 <ul style="list-style-type: square;">
107 <li>calculate the mean values of T0, RMS, Q for each pad, using
108 the AliMathBase::GetCOG(...) function</li>
109 <li>fill the calibration storage classes (AliTPCCalROC) for each ROC</li>
110 (The calibration information is stored in the TObjArrays fCalRocArrayT0, fCalRocArrayRMS and fCalRocArrayQ</li>
114 <h3><a name="user">II. User interface for filling data</a></h3>
116 <h4>To Fill information one of the following functions can be used:</h4>
118 <ul style="list-style-type: none;">
119 <li> Bool_t ProcessEvent(eventHeaderStruct *event);</li>
120 <ul style="list-style-type: square;">
121 <li>process Date event</li>
122 <li>use AliTPCRawReaderDate and call ProcessEvent(AliRawReader *rawReader)</li>
126 <li> Bool_t ProcessEvent(AliRawReader *rawReader);</li>
127 <ul style="list-style-type: square;">
128 <li>process AliRawReader event</li>
129 <li>use AliTPCRawStream to loop over data and call ProcessEvent(AliTPCRawStream *rawStream)</li>
133 <li> Bool_t ProcessEvent(AliTPCRawStream *rawStream);</li>
134 <ul style="list-style-type: square;">
135 <li>process event from AliTPCRawStream</li>
136 <li>call Update function for signal filling</li>
140 <li> Int_t Update(const Int_t isector, const Int_t iRow, const Int_t
141 iPad, const Int_t iTimeBin, const Float_t signal);</li>
142 <ul style="list-style-type: square;">
143 <li>directly fill signal information (sector, row, pad, time bin, pad)
144 to the reference histograms</li>
148 <h4>It is also possible to merge two independently taken calibrations using the function</h4>
150 <ul style="list-style-type: none;">
151 <li> void Merge(AliTPCCalibSignal *sig)</li>
152 <ul style="list-style-type: square;">
153 <li>copy histograms in 'sig' if they do not exist in this instance</li>
154 <li>Add histograms in 'sig' to the histograms in this instance if the allready exist</li>
155 <li>After merging call Analyse again!</li>
160 <h4>example: filling data using root raw data:</h4>
162 void fillCE(Char_t *filename)
164 rawReader = new AliRawReaderRoot(fileName);
165 if ( !rawReader ) return;
166 AliTPCCalibCE *calib = new AliTPCCalibCE;
