    keyword=re: DT in datamon

    I think Alex was the last to adjust the algorithm for deadtime in datamon. *IF* it is the same
    algorithm as in the halog end-run script it would give the same numbers, so perhaps it is
    not the same ? Anyway, if you are worried about DT, add a printout from THaNormAna
    class in the analyzer to print out at the end of a run's analysis. This is the right way to get
    the DT. For online we have a hard time because we don't know -- online -- how many
    triggers of each type are accepted by the DAQ. So the algorithm estimates it by assuming
    certain correlations between the triggers, and there are many correlations at present.
    But these correlatons may not be 100%. Offline, this problem disappears.
