[Eg6_analysis] Coherent DVCS paper from eg6 run group

[Hovanes Egiyan]

Hi Raphael,

this is really great! Here are a few comments:

1) In the abstract there is a statement about the BSA size relative to 
the BSA on the proton, but there
is not such statement or comparison in the article (I might have missed 
it). I would suggest either removing
this statement from the abstract or add graph(s) comparing the two BSAs 
to support such a statement.
2) line 36 : "allowed extraction of the tomography of the nucleon" could 
be changed "allowed for extraction
of the three-dimensional picture of the nucleon" . The way "tomography" 
is used in lines 24 and 37 is a little
unusual.
3) line 49 : "hand bag diagram" -> "hand-bag diagram"
4) line 78 : I suggest removing "and that the reaction did not occur on 
a bound nucleon".
5) line 80 : CLAS was not designed for study of DVCS, therefore the 
statement that it is optimized for DVCS
is not a justified statement. One can simply say " ... in Hall-B at 
Jefferson Lab has been previously used for DVCS
measurements on nucleon."
6) Line 194 : "and a solenoid." -> "and a solenoid magnet."
7) Line 198 "... 5 Tesla solenoid ..." -> "... 5 Tesla solenoid magnet 
... "
8) Figure 3 : The histograms titles need to be removed from the top of 
the graphs and put as x-axis titles.
9) Line 196 " ... that depends ..." -> "... that depend ..." .
10) Line 152 and line 198 : The font for 'He4 changes throughout the paper.
11) Figures 3, 5, 6, 7 : axis titles labels and legends are totally 
illegible. At some point these will have to be improved.
12) Line 271. I am not sure how the results in Figure 7 support the 
argument that the extraction of CFF is
model independent. The applicability of Eq. 5 presumably determines if 
this extraction is model independent or not,
either way the fits would produce some results.

Best,
     Hovanes
