Hi Barbara

Thanks for your suggestion, Please find my rely inline. and new version 
of slides are in the same link

Here I want to more focus on the hot medium effect. so I did not mention 
CNM.

Sure, It will be good that Yu-Ming can prepare one page of slides for 
the procedure.
The graphic is from Yu-Ming's preliminary request slides, I think it is 
efficiency weighted.

ok

The combination is not just combine the final physics data point, But do 
the extraction from the beginning.
and the stat. and sys. are all needs re-calculation.
I did not put sys. uncertainties for the Au+Au results, the error bars 
are just stat. uncertainties.
But the sys. uncertainties is small for Au+Au.

I need to do some change to have this results. Let's us see, If I can 
have the final results next week.
