[Clascomment] OPT-IN: Deep exclusive pi+ electroproduction off the proton at CLAS

[Enzo DeSanctis]

The found the paper interesting and well written.
I have only the following minor remarks:
-  page 1: I will move the sentence 'Here, e and e' ... of the size target.' at lines 33-36 immediately after '...interesting.' al line 27.
-  page 3, Fig. 2 caption: I would drop the last word 'system'.
-  page 4, line 55, I would use the symbol  'p_pi' instead of 'pi' for the four-momentum of the pion, as it is done on line 50 of page 6.
-  page 14, caption of Fig. 14: I would repeat also here that the figure is the low t range of Fig.13.
