[Clascomment] OPT-IN:Longitudinal target-spin asymmetries for deeply virtual Compton scattering

[Lawrence Weinstein]

Overall this is an excellent well written paper.  I have a few concerns:
 1) the description of CLAS is much shorter and less complete than other papers.  The IC is not described at all.
 2) the t-bins are not specified except on the horizontal axis of figure 3.  Figure 2 states that the columns correspond to t-bins but the bins are not specified
 3) the symbols in figure 3 panel 6 are too small and difficult to distinguish from each other
 4) line 340: replace 'prevalenec' with a word like 'dominance'
