how were these data analyzed? Are the time windows for the DCs
trimmed to the same values that Veronique showed to day, ~250ns
for R1, ... or did you use the standard values that Mac had
included for the data taking, which are larger? The difference
should be significant because of high accidental background. I
don't know what Joseph used in the results he showed today. <br>
<br>
We should have results that can be compared directly. .. apples to
apples....<br>
