STAR HardProbes PWG

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

Hi Nihar,

Yes the change in the central point in the 7-9 GeV bin is due to the bug fix, 
but the point before and after is still self-consistent within uncertainty. 
I’ll send the Drupal link to the list in a moment.

Thanks,
Isaac
