[Clascomment] OPT-IN: Probing High Momentum Protons and Neutrons in Asymmetric Nuclei

[Reinhard Schumacher]

Hello Meytal et al.,

I have looked over your draft CLAS paper "Probing High Momentum
Protons and Neutrons in Asymmetric Nuclei", undated, but posted around
11-20-17.   I understand that you want to sent it to Nature, hence the
non-PhysRev styling.    Here are my comments on the paper.  Most are
about grammar and usage, but a couple relate to the description of the
analysis. 

It is very nicely written, in a good, informal style.   What bliss to
be able to off-load all the complicated stuff to "Online Supplementary
Materials"!  The paper has not a single equation in it.   I did not
look at this supplemental material.

Fig. 1 caption:  Use "The electron beam travels FROM THE LEFT along
the gray pipe..."   because the ininitiated viewer can't tell what she
is looking at.   Also use:  "TWO segmentS OF CLAS"  because that is
closer to the truth.

page 2 line 5: the use of "other" seems a bit strange.   How about
"various", so that the present work seems like a natural outgrowth of
the program.

page 2 line 30:  delete "remarkable":  let the reader judge, rather
than tooting your own horn.

page 3 line 22++:   It is not clear where the quoted percentages 90%
15% 5%, and later 85% 15% come from.   Are these Monte Carlo estimates
or estimates from data?   How did you detmine the amount of
"contamination" and what is it?

page 3 line 55:  the sentence end awkwardly.  Try "...cross section).
Figure 2 shows these two..."

page 4, line 4:  It's not clear where the 20% number comes from.

That's all for this round.

Cheers,
Reinhard
