[Clascomment] OPT-IN: Subthreshold photoproduction of phi mesons from deuterium

[Marco Mirazita]

pag 1, left column, second paragraph, row 9
\"..., is a another ...\"  -> \"..., is another ...\"

pag. 1, right column
I would rearrange the paragraph where Fig. 1 is explained. After row 14 (\"... K+ K- production.\") I would put the sentence starting in row 25 (\"The best way to ..... , and proton.\"), then the last sentence of the paragraph (\"The total momentum of ..... in the process.\"), then the sentence starting in row 27 (\"The simulations were ..... on a copper target.\"), and finally go on with the rest of the paragraph from row 14 (\"In Fig. 1 .....\").

pag. 2 
The symbol for the pentaquark should be \\Theta (capital).

pag. 2, left column, last paragraph.
The discussion why the phi threshold in CLAS is higher than its nominal value is not much clear (at least for me). Is it because for photon energy below 1.75 the negative kaon cannot be detected?

Pag. 3, Fig. 3
For better clarity, I would remove the full circles from the histogram.

Pag. 3, right column
In the discussion of systematic uncertainties, you always quote a minimum and a maximum value, but you give only two values of cross section, so is the max value corresponding to one of the two cross section and the min value to the other one?

pag. 4, Fig. 4
Why don\'t you combine together the two measurements from low and high field?
