Greetings Lei,<br>
<br>
All final state particles are detected and preliminary it does not
appear that this factor is localized to a region.<br>
I am currently trying to do a rebin, but for preliminary purposes I
have linked some plots.<br>
<br>
As I have stated, I am trying to rebin in the bins of the plot of
the known cross section. Which are taken from <br>

I do not see a CLAS publication on the rho0 cross section for
photoproduction, nor do I see anything newer than what I have linked
above.<br>

<div>Is your final state p pi- pi+ all detected? Do you have the
same conclusion that for Egamma > 3.6 GeV, there is no
correction factor, and the only correction factor (1.7) are for
the lower beam energies?</div>

The number I will provide is for comparison with Johann,
where he derived a factor of 4.17, I am deriving a factor
of 1.7.<br>
There will be no numbers published until the reason for
the discrepancy is discovered, and once it is discovered,
we have planned to write an fully detailed account of our
methodology.<br>

There are many details that need to be done
correctly, and unless you provide the details (what
bin sizes you used, what files you used, how the
acceptance was calculated, what trigger correction
is applied, etc.) then it’s no help to know what
factor you need. While I’m not proposing that you
write a full analysis note, you should at least say
what you did to get your cross section.<o:p></o:p></p>

I have compared my cross section visually and it
appears that if I needed a correction factor it
would be no greater than 2. I will supply the
plots later as I am currently working on it.<o:p></o:p></p>
