600/10000, if assuming the number of generated events in the normalization as Holly does. That makes a larger difference.<br class="">

<div class="">Thanks for this Bradley, Good to have official numbers!
<div class=""><br class="">
</div>
<div class="">For events/file, that is basically what I’m using (*10 because I use DSTs)…I’ll switch to 590 from (600); that’s <2% though for me. </div>

<div dir="ltr" class="">Hi all,
<div class=""><br class="">
</div>
<div class="">This past week I showed the rad frac at 12% with vertex cuts. I had not accounted for alpha difference in radiatives (I thought these were generated with correct alpha, but it seems they are not). </div>
<div class=""><br class="">
</div>
<div class="">In any case, I now calculate rad frac to be 9% which seems consistent with Omar and Matt S. </div>
