[Clascomment] OPT-IN:Beam-target double spin asymmetry in quasi-elastic electron scattering off the deuteron with CLAS

[Daniel Carman]

Mike and Sebastian,

I have read through the draft of your e-D double spin asymmetry paper paper that
was posted for review. I include here my comments. Let me know if you have any 
questions.

General:
 - For figures that are not B&W, you should include "(Color online)" in the caption.
 - You are not consistent with your usage of S-state and D-state vs. $S$-state and
   $D$-state.
 - You are not consistent with your units. For the missing mass you consistently
   use units with c=1.
 - You are not consistent with usage of $p_m$ vs. p$_m$.
 - You are not consistent with usage of versus, vs., and $vs.$.
 - You are not consistent with usage of Eq. # vs. Eq.(#).
 - You are not consistent with usage of $D$ vs. D vs. $^2H$ in your target notation.

Page 14:
 - Table V caption and column label. Use "$Q^2$".

References:
 - Put references in the order that they are cited in the paper.
 - Do not include preprint numbers for already published papers.
 - Ref.[22] is a CLAS Collaboration paper.
 - Ref.[33] is a CLAS Collaboration paper.
 - Notation problem in Ref.[42].
 - Ref.[44] should be "B.A. Mecking ...".
 - Use "CLAS Collaboration" in Ref.[46].

Tables VI, VII, VIII, IX:
 - All caption titles should end in a period.
 - The number of significant figures in these tables is not appropriate. They should be
   listed only to the relevant accuracy, likely only 3 numbers past the decimal place.
