Hi Eugine and all
glad that the difference disappeared. all I did was ran the old
wc_res.C macro.
Your analysis appparantly have a lot more in it.
I am not sure how to take Chris's message in which he said no difference was
found. we ll see in the meeting.
BTW, in 2004 data, I have a 2.4 sigma dip in parallel kinematics at 0.2GeV/c^2
which becomes 2.7 sigma in the recrunch. Ofcourse 2.4 is nothing better than
2.4. the anomaly seemed to have started in Oct of 2004 but disappeared in 2005
data set. Fortunately, the 2005 data has much stronger statistics so the final
result look OK. I will discuss this in the meeting.
I will stick to the old crunch as it at least SEEM to be more consistent.
