[Deeppwg] APS Talk

[burkert]

Wes,
 you have a very nice talk.  However, your acceptance corrected 
phi-distribution for pi+ on slide #12 cannot be correct. It would seem 
that the acceptance function that was used does not really describe the 
acceptance well as the two unphysical "bumps" located symmetric around 
180deg clearly show. The result is that your reduced chi^2 for the fit 
with the phi parameterization to the pi+ data is ~10, while for the pi- 
you have a much better chi^2 ~ 1.  The moments for pi+ are then also 
suspect. I suggest not to show the pi+ distribution as it may prompt 
questions.
You probably have too many slides for a 10min talk. You may want to drop 
2 or 3 slides.
Good luck!
Volker
