<li class="li1" style="mso-list:l3 level2 lfo1">Byproducts of the upgrade to CODA 3.10 and my misunderstanding. It affected NPS only. And now it’s fixed.<o:p></o:p></li><li class="li1" style="mso-list:l3 level2 lfo1">In the Fall run, this affected about ~5%<span class="apple-converted-space">
</span>with two different causes<o:p></o:p></li><li class="li1" style="mso-list:l3 level2 lfo1">The hypothesis is that Helicity scalers are not affected. Bob is close to proving this right; they needs a few more weeks of work.<o:p></o:p></li><li class="li1" style="mso-list:l3 level2 lfo1">Bob showed examples of good and bad runs with respect to this problem<o:p></o:p></li><li class="li1" style="mso-list:l3 level2 lfo1">Comparing the helicity scaler reading to the “regular” scaler helps identify runs with bad regular scalers.<o:p></o:p></li><li class="li1" style="mso-list:l3 level2 lfo1">Bob showed a list a remaining TO-DO list (last list)<o:p></o:p></li></ul>
<li class="li1" style="mso-list:l3 level1 lfo1">Open questions: does the helicity scaler report the EDTMs? Yaopeng and Bob will look into that.<o:p></o:p></li></ul>

Casey suggests investigating the multiplicity and possibly the trigger type.<o:p></o:p></li><li class="li1" style="mso-list:l0 level1 lfo2">Charles and Casey suggest enlarging the good timing windows to make sure not to lose any events.<o:p></o:p></li></ul>
