Hi,
I looked over your note again.  I am glad to read it with good agreement.

Here is my comments.

(1) page2 : there is no missing momentum plot and cut but you mentioned 
in text.
(2) page3 : Fig 1. you have identical TOF mass2 plot (no negative mass)
(3) page4 : Section4.2:  Could you point out what exactly mean at last 
sentence. ("Their application does not change the main conclusion of 
this....")
(4) page6 : top-para.. \Delta M=100MeV => \Delta E=100MeV
(5) page6 : bottom-para... t-slope of t = 3 was a better .... : As far 
as I remember you mentioned you got the best result with t=4 in 
simulation. Didn't you ?
(6) page10: "We expected a smoother distribution.....it will become 
smoother".  Are you saying that you need more simulation ? I think you 
already had very nice smooth distribution.
(7) page17: Suddenly you talked about G11 trigger configuration in the 
bottom of page17.  You had better put this para into somewhere with EG3 
trigger configuration.
(8) page18: "This efficiency map is ....next section....". =>  no proper 
section
(9) page18: text before after Table 1, typo: table 2 => table 1
Table 2 outlines all corrections.... => Table 1 outlines...
 From the table 2, all correction.. => From the table 1, all correction...
(10)page18: Table1 : missing momentum cut and missing mass cut are not 
in the table.
(11)page19: bottom : "The \Delta++ cross sections still ..." :  what 
kind of discrepancies you're  talking about.
(12)page20: typo : right after Fig.17) K\Lambda\pi q(4 track, ...   => 
K\Lambda (4 track, ...
(13)page24: title of table 2 : Average Correction Value... => Average 
efficiency correction value...
(14)page24: Table shows the runNumbers and ... => Table 2 shows the 
runNumbers and ...
(15)page24: table 2 : 45552-45627(Before X-mas) 45804-46113(After X-mas)
(16) page24:last para:  SAPHIR data is not rho separation (using Soding 
model), so you can't say pure Delta++.
Our bot EG3 and G11 data agree with SAPHIR data Not  "SAPHIR produces 
good agreement between ...."
(17)Fig 23,  24 G11 data legend is wrong.

** I can provide you ps or eps file for better resolution if you want.

Sincerely yours,
Kijun
