[Clascomment] OPT-IN: First-time measurement of Timelike Compton Scattering

[Igor Strakovsky]

Dear Pierre,

I have read through the draft of your CLAS12 paper on TCS targeting Phys. Rev. Lett. and have several minor comments.

1) Your Fig 3 shows the invariant mass spectrum with three visible signals of \omega/\rho,\phi, and J/psi vector mesons.  There is one more signal around 2.6 GeV.  Can you clarify who this guy is, if possible?

2) Your Figs 5 - 7 show asymmetries while your fig captions indicate "BH amplitudes contributing to the cross sections". It is unclear how it works.  Then the symbols (red open triangles) may indicate that BH is data.  Then what horizontal bars mean?

3) Finally, for the same figures you show predictions using different models.  I am sure that the authors generated predictions upon your request.  If that is the case then they deserve acknowledge

Thanks, Igor
