STAR HardProbes PWG

[suyuann AT mail.ustc.edu.cn]

Dear conveners,

Thanks Yi and Isaac for the constructive comments and sign off. I am still 
waiting for Nihar's comments.
Please find our responses and revised paper draft at:
https://drupal.star.bnl.gov/STAR/blog/suyuann/RepliestoPWGCpreviewD0RAAisobar

We would like to push the D0 R_AA in isobar results and paper for further GPC 
review. Please help us to form the GPC. Thanks.

Best regards，
Yuan
