- page 2, line 105, the CLAS calorimeter polar angular range for photons is 8 to 45, it became 15-45 due to IC. The sentence should be corrected, to clarify that
- page 2, line 144, sentence "In order ... we chose to minimize the size of our bins, ...". Can you give the value of minimized bin size the resolution of the detector for that variable
- page 3, line 184, "... of 12.3%, meant to compensate for various effects that 185 are not well reproduced by the simulations". This means it either comes from efficiency calculation or radiative effects. Both effects will be very different for elastic events. is not it. How elastic with very different kinematics can be used for this arbitrary correction
- one of interesting results from Hall-A measurement was Q2 independence of the Im-part of the Compton FF, that was attributed to twist-2 dominance. It seems we have much more data to say something with respect to this important question. Why we are not giving Q2 dependence? Is it because there is not enough statistics in any of x-bins to have few Q2 points?
