Hi, Lewis.
Here is my comments on the latest version note (May,20.2010).

(1) page 19,20: You mentioned the trigger correction factors with 4.5 
and 5.3 but 6.4. Which one is the last one in our final analysis ?
(2) page 25 : last part, 9% level => 15% level.
(3) Table 2. Untriggered Tagged Region Correction : 6.4 => 4.5/5.3/6.4
You remarked only 6.4 here, it seems to me our final correction is 6.4
(4) Table 2. Missing momentum cut for EG3 : MMom < 2GeV => Are you sure 
? not 0.2GeV
(5) Relatively, text under the Table 2, you're saying that
"The only difference shown between the aaplications us the G11 trigger 
efficiency ...." I think there is two more difference in terms of 
correction between G11 and EG3, which are (a) 2ns tagger cut correction 
(b) z-vertex cut.
(6) It just for my understanding....There is no explanation about 
multiple hit correction between Fig14 and Fig19, which means Fig14 
(bottom) and Fig19 should be same. But Fig 19 is higher than Fig14 due 
to multiple hit correction. I think it should be explianed in text 
somewhere between.
(7) page 28, 4th row from top; "...fromt he..." => "...from the .."
(8) page 28, 5th row from top, "t-counter" => "T-counter"
(9) page28, Section 5.2; "...were compared to existing CLAS data..." => 
"...were compared to other CLAS data..."
(10) page 28, Section 5,2; "In Figure 20, the magenta ....." => "In 
Figure 20, the magenta closed circles .... blue open circles ...."
(11) page 28, Section 5,2; "From Figures 22-24 displaying ...." => "From 
Figure 25 displaying ...."
(12) page 28, Section 5,2 (very bottom); For better my understaing, how 
you get 6% in maximum uncertainty ?
(13) page 30; Table 3 => should be removed...
(14) Fig 25, in caption ; Saphir( ) => SAPHIR( ), symbol should be 
corrected with "full square"
(15) For me, I am not sure whether we have to show Fig 28, 31.

Sincerely yours,
Kijun
