[Clas_lmd] LMD Meeting October 22 2013

[Michael C. Kunkel]

Greetings,

I have completed the data analysis part of the eta->3pi with the cuts 
provided to us at Tuesdays meeting.
Unfortunately the eta topology with these cuts looked very poor, see fig 
0.1  at https://wiki.jlab.org/lmd/index.php/Michael_C._Kunkel

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.
The only cut needed now would be a Pull Probability cut, which I took to 
be above 10%, see fig 0.2  at 
https://wiki.jlab.org/lmd/index.php/Michael_C._Kunkel

I would like to know if the kinematic fitted spectrum is acceptable so 
that I can give these events in gamp format.

Please try to respond to this email, so that I may make the deadline I 
promised.

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.
