0ab2a4cc 20 July 2011:
21
22 Changes to accomodate updates of general DQM/QA changes to have per trigger
23 histograms (for a given event specie).
24
25 AliTPCdataQA has a new flag for only keeping DQM info event by
26 event!
27 The expert/DA functionality has been kept exactly the same!
28
29
1267cf3a 30 June 2010
31
32 This update should solve two problems mainly:
33 * The vs event histograms have been limited to a fixed size for the
34 DQM. The 500k seemed to be a big size but is no longer so, so we
35 need to dynamically expand the range. The non-trivial point is that
36 we also have to do it for the copy owned by AliTPCQADataMakerRec.
37 * The amoreGui now remembers the x-range of the first visualization so
38 the trick of setting the relevant event range as the histogram is
39 filled no longer works.
40
41 The fix is a bit crude but avoids creating a new histogram. Instead
42 the range is expanded (max events and events per bin is doubled) but
43 the number of bins is kept constant! In this way we can change just
44 double the max of the X-axis of the hist and rebin the data. The
45 same can easily be done for the copy owned by AliTPCQADataMakerRec.
46
47 CAUTION:
48 If we change the number of bins we could crash the whole system
49 because ROOT does not create space for extra bins! (but we do not do
50 this). In that way it is a crude solution.
51 The rebinning in the code only works for an even number of bins.
52
53 In addition to the above a bug in the reading of the config file was
54 also found and corrected. fAdcMax was set instead of fEventsPerBin.
55
56 Finally cout was changes to AliInfo.
57
266f8637 58 February 2008
59
60 The code has been heavily modified so that now the RAW data is
61 "expanded" for each sector and stored in a big signal array. Then a
62 simple version of the code in AliTPCclustererMI is used to identify
63 the local maxima and these are then used for QA. This gives a better
64 estimate of the charge (both max and total) and also limits the
65 effect of noise.
66
67 Implementation:
68
69 In Update the RAW signals >= 3 ADC channels are stored in the arrays.
70
71 There are 3 arrays:
72 Float_t** fAllBins 2d array [row][bin(pad, time)] ADC signal
73 Int_t** fAllSigBins 2d array [row][signal#] bin(with signal)
74 Int_t* fAllNSigBins; 1d array [row] Nsignals
75
76 This is done sector by sector.
77
78 When data from a new sector is encountered, the method
79 FindLocalMaxima is called on the data from the previous sector, and
80 the calibration/data objects are updated with the "cluster"
81 info. Finally the arrays are cleared.
82
83 The requirements for a local maxima is:
84 Charge in bin is >= 5 ADC channels.
85 Charge in bin is larger than all the 8 neighboring bins.
86 At least one of the two pad neighbors has a signal.
87 At least one of the two time neighbors has a signal.
88
89 Before accessing the data it is expected that the Analyse method is
90 called. This normalizes some of the data objects to per event or per
91 cluster.
92 If more data is passed to the class after Analyse has been called
93 the normalization is reversed and Analyse has to be called again.
