STAR QA Board

Hi Frank and all,

For slides 16-18, I only want to show that it's the same that the 
average value of those variables in SL18c and SL20c for this particular 
run number dataset that I analyzed (I didn't run the other run number 
data). I should only show one run index on the y-axis, sorry for the 
misleading label.

Thanks,
Yingjie
