[G14_run] G14_run Digest, Vol 74, Issue 3 (Tuneo's question to K Sigma analysis note)

[Tsuneo Kageya]

Hi Nick,

 Sorry to be late to make a question.
 I have a question about the systematic error calculations.

 At page 35, on the table 4, you calculated the total absolute systematic error
to be 0.10.   How this is reflected into the total relative systematic error ?
On the pi-p analysis, I think we calculated the systematic errors from cuts in
the similar way and they are combined to the other errors (target and beam polarizations).
Is this number 0.10 means 10 % or 0.1 % ?

 I may misunderstand this issue.  Please let me know.

    Regards, Tsuneo Kageya.

Hi Nick,

Indeed, noticeably improved.?? I recommend that you put the horizontal 
error bars on Figs.? 29 - 32, too.? They are just as important there 
since the model curves can vary a lot across one bin.

Hi Reinhard, 

The figures looked a bit busy when I did that (too many lines) and thats why i left the x-uncertainties out in those, but its takes me 2 minutes to incorborate them. I think that will be more relevant when we decide exactly how to present our results in the publication. 

In the meantime I was wondering if its OK with the group to share our preliminary results with the theorists and see if we can get any insights from them.

Best regards,
Nick
