[Clascomment] OPT-IN: Precise Determination of the Deuteron Spin Structure at Low to Moderate Q2 with CLASand Extraction of the Neutron Contribution

[David Ireland]

Dear Nevzat, Sebastian, et al., 

This is a very nice paper that should not be difficult to get published.

I have just a few minor comments (April 17 version):

- Abstract, line 1: Perhaps replace "the final results" with something like "comprehensive results". It currently reads like this will never, ever be measured again!

- There are a couple of instances of jargon that might need to be made more explicit:
- line 76: Replace "EG1-DVCS collaboration has published precise results on the proton..." with "the CLAS collaboration has published precise results from the EG1-DVCS run on the proton...
- line 892: Hall C -> Jefferson Lab Hall C

- You refer several times to companion results, which are not yet published. It is certainly more work, but shouldn't the first (chronologically) published paper contain these details, which can be referred to by subsequent papers?

- Also, what does the Supplemental Material contain? Is it not appropriate to include it in this (long) paper, or is there simply too much?

-line 593: is there a typo here? I do not see a data point at P_bP_t = 0.1 on Figure 5.

-lines 793-796: Sentence maybe needs rewording or removing, since the meaning could be interpreted as "two precise data sets from the same collaboration do not agree with each other". Is it enough to leave the statement that the kinematics are different? 

- Figures 15 and 20 are counter-intuitive for me. The blown up scale at low Q2 may be better on the left hand side.

- line 1027: forth -> fourth

- line 1115: two decades -> two orders of magnitude


Best wishes, 

Dave
