sPHENIX HCal discussion

[Craig Woody <woody AT bnl.gov>]

Hi Edward,
  Yes, I agree. That bothered me too, even though it seems to be a 
small effect and may just be an artifact of not knowing the absolute 
energy scale well enough. I'll talk with Jin about it and see what we 
can come up with.

Thanks,
Craig
