91 | ||
92 | <h4>Raw laser data is processed by calling one of the ProcessEvent(...) functions | |
93 | (see below). These in the end call the Update(...) function.</h4> | |
94 | ||
95 | <ul style="list-style-type: square;"> | |
96 | <li>the Update(...) function:<br /> | |
97 | In this function the array fPadSignal is filled with the adc signals between the specified range | |
98 | fFirstTimeBin and fLastTimeBin for the current pad. | |
99 | before going to the next pad the ProcessPad() function is called, which analyses the data for one pad | |
100 | stored in fPadSignal. | |
101 | </li> | |
102 | <ul style="list-style-type: square;"> | |
103 | <li>the ProcessPad() function:</li> | |

105 | <li>Find Pedestal and Noise information</li> | |
106 | <ul style="list-style-type: square;"> | |
107 | <li>use database information which has to be set by calling<br /> | |
108 | SetPedestalDatabase(AliTPCCalPad *pedestalTPC, AliTPCCalPad *padNoiseTPC)</li> | |
109 | <li>if no information from the pedestal data base | |
110 | is available the informaion is calculated on the fly | |
111 | ( see FindPedestal() function )</li> | |
112 | </ul> | |
113 | <li>Find local maxima of the pad signal</li> | |
114 | <ul style="list-style-type: square;"> | |
115 | <li>maxima arise from the laser tracks, the CE and also periodic postpeaks after the CE signal have | |
116 | have been observed ( see FindLocalMaxima(...) )</li> | |
117 | </ul> | |
118 | <li>Find the CE signal information</li> | |
119 | <ul style="list-style-type: square;"> | |
120 | <li>to find the position of the CE signal the Tmean information from the previos event is used | |
121 | as the CE signal the local maximum closest to this Tmean is identified</li> | |
122 | <li>calculate mean = T0, RMS = signal width and Q sum in a range of -4+7 timebins around Q max position | |
123 | the Q sum is scaled by pad area (see FindPulserSignal(...) function)</li> | |
124 | </ul> | |
125 | <li>Fill a temprary array for the T0 information (GetPadTimesEvent(fCurrentSector,kTRUE)) (why see below)</li> | |
126 | <li>Fill the Q sum and RMS values in the histograms (GetHisto[RMS,Q](ROC,kTRUE))</li> | |
127 | </ol> | |
128 | </ul> | |

136 | <li>calculate the mean T0 for side A and side C. Fill T0 histogram with Time0-<Time0 for side[A,C]> | |
137 | This is done to overcome syncronisation problems between the trigger and the fec clock.</li> | |
138 | <li>calculate Mean T for each ROC using the COG aroud the median of the LocalMaxima distribution in one sector</li> | |
139 | <li>calculate Mean Q</li> | |
