OPT-IN: Measurement of two-photon exchange effect by comparing elastic e± p cross sections

[Stepan Stepanyan]

line 260 - should be "... toroidal magnetic FIELD ..."
line 316 - is "a" needed before "TPE collimator"?
line 343 - should it be "... to each OTHER ..."?
line 391 - "d" is missing, should be "distribution"
Fig. 10 - fit looks really ugly, the peak position of the red histogram is shifted left compare to
Gaussian function. The correct way os to fit with some background function or limit upper edge
of the fit to lower W.
line 567 - how you deal with non-gaussian form of E- for +/- 3\sigma cut
