Class Description
Chip Tracking Trigger Engine ============================ Tracking trigger built in front end chip. The algorithm searches for sequences of pixels (over the threshold) consequtive and adjacent. If the track length is over a threshold, trigger occurs. The algorithm searches also between track segments of two nearby chips: if two track segments are consequtive in time and the total length is over a threshold (different from the previous one), trigger occurs Parameters: fThresholdType: specify if the threshold on pixel hits in a gtu is absolute or relative Valid options: - absolute: the value specified in fThreshold is the minimum number of hits in a gtu to consider - relative: trigger threshold depends by the mean value of the background hits (B) in each pixel: threshold = (B) + fThreshold*sqrt(B) fThreshold: threshold on pixel hits in a gtu; if fThresholdType=relative the true threshold used by trigger algorithm depends by the mean hits of background in each pixel (see above) fMinTrackLenght: min length of the valid tracks fMaxTrackLength: max length of the valid tracks fMinTriggerTrackLength: min track length to have a trigger (single chip) fMinTriggerTwoLength: min total track length in 2 nearby chips fMaxTwoLength: max track length allowed in 2 nearby chips fAcceptHole [bool] : an hole in a single track segment is or not accepted fOnlyWithSignal [bool] : processes or not only chips ith at least a signal
