Hey Brad,<br><br>I wanted to show you my latest fidgeting with the S2m timing, and the resulting beta. S2m time offset looks nice now -- very flat. I think the corrected time average looks good too, but maybe I can play with the remaining jitter there -- though it looks to be ~1-2 ns. This seems to be the last place to make corrections so that I could get the tail on the higher end of beta to reduce more, since it's these time averages of S1, S2m that contribute to beta. I don't think the time offsets need any more work.<br>
<br>The last two plots are TDC (ns) vs. ADC (ADC channel units) -- to follow up with what we were talking about in the meeting. I think the timewalk is much clearer here than TDC vs. 1/sqrt(ADC). This is especially true for S1, and that strange behavior we saw in S2m I believe shows up here at ADC ~ 0 -- that thick section of entries along the TDC axis...<br>
