[Clascomment] OPT-IN: Demonstration of a novel technique to measure two-photon exchange effects in elastic e(+/-)p scattering

[Stepan Stepanyan]

Dear Larry et al.,

Few minor questions and comments:
- page 5, left column, last paragraph, I understand notation B=+/-0.4T for Italian magnets, since the had different
polarity, but why B=+/-0.38T for pair spectrometer magnet. As you point in the text, chicane polarity was not changed, and therefore pair spectrometer was run at one polarity, is not it?
- how start time was determined for event, like for ++ case
- page 9, right column, first paragraph of subsection B, line 3, better to sat "on lepton charge" instead of "on lepton polarity"
- page 11, left column, second paragraph, line 2, "this narrow a range of", should it be "this narrow range of"
