[Clascomment] OPT-IN: Measurement of the nucleon spin structure functions for 0.01 < Q2 < 1 GeV2 using CLAS

[Alexandre Deur]

Dear Patrick and All,

Thank you for pointing this out. In fact, both denominations "virtual photon flux" and "virtual photon equivalent energy"  are routinely used for K. For example, the textbook of R. G. Roberts "The structure of the proton" uses "flux", while the Thomas-Weise textbook "The structure on the nucleon" uses "equivalent energy".

We have thus modified this part of the manuscriot, which now reads:
"The virtual photon equivalent energy K (sometimes called virtual photon flux)
in Eqs. (8-9)"

I hope this adequately takes care of the issue. Please let me know if not.

Best regards,

Alexandre, also for Marco, Xiaochao and Sebastian

After a very short glimpse at the paper:
"The virtual photon flux K in Eqs. (8-9)..." This variable is indeed not observable, so it's naming is not very relevant, but it is better called an energy, e.g. virtual photon energy or photon equivalent energy.
