Most of the comments are easy to answer. Only one comment requires some work. This is about trigger in case of untagged real photon. I  guess this question came from Marco.
This is legitimate concern we should address. Simple two prong trigger with no FT will overwhelm DAq. 
The trigger may be [2-prong AND FT]OR[4-prong] We nee to look what is the rate of 4-prong events. compared to 2-prong AND FT.
I guess this asks for some simulation.

Hi, All,

I have received the comments from Ken. Most are minor comments. There is a bit of problem in the trigger/untagged photon rate that could be due to some miscalculation.

Let's look at the comments and meet this Friday? Or maybe sooner? 

Lei
