Class Description

BrTpcSequencePPModule()

 Default constructor. DO NOT USE

BrTpcSequencePPModule(const Char_t* name, const Char_t* title) : BrModule(name, title)

 Named Constructor

void ApplyTimeAndAdcCuts(BrTpcSequence *seq, TObjArray *outTable)

 This method takes a sequence as input. It removes the part of the
 sequence below and above the fTimeCutLow and fTimeCutHigh and the
 bins where the Adc values are below fAdcMin

 The algorithm used is to define an array of shorts called split
 For each bin in the valid range a number is given to groups of
 consecutive bins with adc values above fAdcMin. After stepping
 thorugh the whole sequence new sequences are mnade if the
 sequence is at least as long as fMinSeqLength

 Ex :

  Input sequence
  Row :   7 Pad :  41
  Time :  18  19  20  21  22  23  24  25  26  27
  Adc :  152 192  67  55  38  16   5   2   1  -1
          ^   ^
          ___\_____ ignored because of time cut
  Split array :
                   1   1   1   1   1   1   1   0

  New sequences :
  Row :   7 Pad :  41
  Time :  20  21  22  23  24  25  26
  Adc :   67  55  38  16   5   2   1

 To get ouput like this set the debuglevel to 20

void DefineHistograms()

 Define histograms. They are:
 <fill in here>

void Init()

 Job-level initialisation

void Event(BrEventNode* inNode, BrEventNode* outNode)

 Tme event methods modifies the sequence table in the in node, and
 therefore has no special output.

 The strategy is :
 a) throw away sequences in pad strictly less (greater) than
 pad low (high) cut
 b) remove 0 (default) and negative values from sequences by
 cutting them in pieces
  ( -1, 0, 10, 12, 8, 6, 0, 5, 3, 0, 10, 20, 10, 5 )
   ==>
  ( 10, 12, 8, 6 )     &&  ( 10, 20, 10, 5 )
  ( 5, 3 ) is not kept with default parameters since it is only 2 long.
 c) remove the part of the sequences that has time < fCutOffTime
 since a lot of noise was observed there with real data

void Print(Option_t* option) const

 Print module information
 See BrModule::Print for options.
 In addition this module defines the Option:
 d - print original author and who, when modified last
