[Clascomment] OPT-IN: Measurement of the beam asymmetry Sigma and the target asymmetry T in the photoproduction of omega mesons off the proton using CLAS at Jefferson Laboratory

[Stepan Stepanyan]

Nice work, just a few cpmments:
- line 276, definition of \beta_{TOF} is really meaningless, the important aspect of this selection is how one found the velocity. To calculate velocity one needs the time-of-flight and time-of-flight requires knowledge of the event start time, that comes from the tagger, or it is time difference between ST and SC. So, which way time-of-flight was and eventually velocity was calculated? Clear description is required.
- line 281, it is incorrect to say "significant improvement", nothing is really improved, it just cuts applied clean up the \beta vs. p distribution
- line 287/288, is there any energy loss i the target material? why energy loss in the target was not accounted
- line 321 and Eq.(2) and line 331, "Q" is used for two different purposes, as sum of kinetic energies and as a Q-value of the event (S/(S+B)), this is confusing. Will be better to redefine sum of kinetic energies with different letter
- line 352, not sure but I think it should be "goodness of the fit"
- line 411, "rad" must be out of brackets since it relates not only (2.025-\pi) but also \phi_{offset}=2.025
- line 410/411, why present these values in radians and then explain that the correspond to ** degree described above? Why not to write in degrees?
