[Olympus] Next collaboration meeting

[Norair Akopov]

Dear Douglas,

Due to change of Monday to Tuesday for our Monday meeting I can not attend 
for todays discussion at 16:00. I would like to share with my comments 
concerning  "how to proceed"..

- I support points noted in email sent by Alexander concerning necessary 
explanations how the final result was derived, e.g. is it just average 
weithed based on three independent results (Axel+Brian+Rebecca), if so , 
then how the systematics due to difference in three results were 
estimated (also details how the systematics due to left/right asymmetry 
was estimated)?

- I well understand the intention to show as wide as possible Q2 and 
\epsilon measured ranges, BUT saving e.g. 20 Q2 bins for the final result we have 
more than 1% stat. error at last 3 (even 4) Q2 bins? How this corresponds 
to the declared less than 1% total uncertainty ? In my opinion better to 
have just 8 Q2 and \epsilon bins (which is anyway compatible with the 
number of points measured by JLab and remarkably larger than the number of 
points measured by Novosibirsk). Making so as to my estimation we should 
have less than 1% stat. errors even at last/first Q2/\epsilon bins. 
Possible option could be to have both: 20 and 8 Q2 bins.

- did somebody estimate the percentage of background as a function of e.g. 
Q2 based on reconstructed beam energy spectra in addition to the 
estimations made with the coplanarity spectra , also how possible 
systematics due to different polynomials used for bck. estimation was 
evaluated ?

Best regards,

Norik
