Greetings,<br>
<br>
For clarity, do you want a single gamp file for the peak and one for
the background,<br>
3 sigma for peak and 0.6 - 0.6 GeV for background, or one gamp file
as your previous email suggests?<br>

<div>Greetings,<br>
<br>
I have completed the data analysis part of the
eta->3pi with the cuts provided to us at Tuesdays
meeting.<br>
Unfortunately the eta topology with these cuts looked
very poor, see nofit_Eta_3pi.pdf attached.<br>
<br>
I took it upon myself to use the kinematic fitter that
Georgie and I have for these events. I fit the missing
spectrum of proton pi+ pi- to that of a neutral pion.<br>
The only cut needed now would be a Pull Probability cut,
which I took to be above 10%, see fitted_Eta_3pi.pdf.<br>
<br>
I would like to know if the kinematic fitted spectrum is
acceptable so that I can give these events in gamp
format.<br>
<br>
Please try to respond to this email, so that I may make
the deadline I promised.<br>
<br>
Also, I estimated the number of events incorrectly in
the meeting. I thought it to be around 150K, I had the
wrong cross section in my head when I estimated it. As
you can see, there are only 16K events.<br>
