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

[Keith Griffioen]

This is extremely nice work and a very important addition to GPD physics.  However, the paper needs a good editing before it goes out the door.  Perhaps I am rather sensitive to this because I have just been correcting several other papers, and I have watched the PRL editors make additional editorial changes to a document I thought was perfect.   A CLAS Collaboration paper, with its many authors, should never be sent to a journal with rough edges.  If the text is not carefully written, any reader subconsciously begins to doubt whether the analysis was carefully done and whether the long list of collaborators actually read the text carefully.  I have made some suggestions in:

Many of my suggestions try to eliminate circumlocutions, remove repetitive content, and add clarity.
I hope this serves as a start of what should be two rounds of editing to make the document shine like the analysis and physics results it describes.

Thanks,
