20 | February 2008 | |
21 | ||
22 | The code has been heavily modified so that now the RAW data is | |
23 | "expanded" for each sector and stored in a big signal array. Then a | |
24 | simple version of the code in AliTPCclustererMI is used to identify | |
25 | the local maxima and these are then used for QA. This gives a better | |
26 | estimate of the charge (both max and total) and also limits the | |
27 | effect of noise. | |
28 | ||
29 | Implementation: | |
30 | ||
31 | In Update the RAW signals >= 3 ADC channels are stored in the arrays. | |
32 | ||
33 | There are 3 arrays: | |
34 | Float_t** fAllBins 2d array [row][bin(pad, time)] ADC signal | |
35 | Int_t** fAllSigBins 2d array [row][signal#] bin(with signal) | |
36 | Int_t* fAllNSigBins; 1d array [row] Nsignals | |
37 | ||
38 | This is done sector by sector. | |
39 | ||
40 | When data from a new sector is encountered, the method | |
41 | FindLocalMaxima is called on the data from the previous sector, and | |
42 | the calibration/data objects are updated with the "cluster" | |
43 | info. Finally the arrays are cleared. | |
44 | ||
45 | The requirements for a local maxima is: | |
46 | Charge in bin is >= 5 ADC channels. | |
47 | Charge in bin is larger than all the 8 neighboring bins. | |
48 | At least one of the two pad neighbors has a signal. | |
49 | At least one of the two time neighbors has a signal. | |
50 | ||
51 | Before accessing the data it is expected that the Analyse method is | |
52 | called. This normalizes some of the data objects to per event or per | |
53 | cluster. | |
54 | If more data is passed to the class after Analyse has been called | |
55 | the normalization is reversed and Analyse has to be called again. | |
