Yes, you are correct: I just integrated the red and black curves for the 
present run and found a 10% difference in counts over a time range from 0.05 
to 24.5 microseconds.

To quote my e-mail of April 20 ("Re: statistics") --
  'What might not be clear is that the "muSC PP" also implies a muSCA veto.'
Does the muSCA veto not account for the difference between your 
10% and my 20%?  The muSCA rate is 3.5 kHz out of our 25 kHz after-kick rate.

Thanks,
