STAR HardProbes PWG

["Mooney, Isaac" <isaac.mooney AT yale.edu>]

Hi Qian,

I think it is at least possible to say something about the different physics 
between the 2nd order event plane and the other two, but if your preference 
is to leave it out that is okay with me. I sign off, and have pushed it to 
STAR-talks.

Thanks,
Isaac
