    keyword=Threshold change on number of hits for RICH

    Since the RICH ROCs are not the limiting ones, you can try to increase
    the maximum of channels read until you see a significant change in
    deadtime. Since the previous deadtime was most likely due to the
    timeout it might not change much. I guess I will reanalyze the runs
    with my program, I got a number close from 7% last time. Since we get a
    bit more of signal the multiplicity might be a bit bigger.One also has
    to be very careful with pedestal and thresholds files since if the
    pedestal are wrong or threshold too low many channels might fire and
    the limit would be reached. Also that would be interesting to see if
    those 7% applies mostly to T3 or to T5 too. But yes I think you can try
    increase the number of channels unless you see significant dead time
    increase. Also since we interleaved the channels between ROCs there is
    still a chance we can reconstruct the event if the other ROC has data.
    I still need to figure out a way to flag those in the tree to see how
    much it affects the reconstruction.
