Hi  all,
I have studied for g11 corrections (the 2nd and 4th) that committee 
mentioned. I have checked out these corrections for Delta++ channel. 
Based on their point of view,  I summarized  what I implemented in the 
g11-delta++ analysis.
(1) Rate dependent for 3 prongs events = 19% (I applied this using by 
CMU group method)
(2) 2ns tagger cut correction = 6% (no applied)
(3) Trigger inefficiency = 15% (I applied this using by CMU group method)
(4) Multiple hit in the tagger within 2ns tagger cut = 18% (no applied)

So, we need to apply two more corrections eventually later. Before 
applying these, I have studied these corrections are consistent with the 
ones from omega-analysis.
For this, I scratched  the method from :

Here, you see what I have.

Basic conclusion:
(1) Two correction factors are consistent with omega-analysis group applied.
(2) Basically two corrections do not depend on photon energy and reaction.

Unfortunately, I will not be able to attend the meeting tomorrow due to 
Dr. appointment. Please let me know your comments after meeting.
Thank you in advance.

Sincerely yours,
Kijun
