    The code segments faults inside the final HistOn() section in the
    BrTrackFinderBase :: FillDetectorTracks()
    Do you have this filling of deviation histograms.
    The code works just fine for TrackFollowFinder that walks through same piece
    of code.
    
    Maybe you could check the modifed Oslo version in, so I can get rid of my
    modification to the code
    
    Thanks for the infor on parameters.
