STAR HardProbes PWG

[Nihar Sahoo <nihar AT rcf.rhic.bnl.gov>]

Hello Tanmay,

Thank your for posting all your preliminary plots.

Please change "A_Jet < 0.03" to "A_jet > 0.3". I think this is a typo as 
you have mentioned AJet > 0.3 in your preliminary request slide7.

Please update this in all your plots.

I will send my comment on your HP2023 slide in a separate email.

Cheers
Nihar
