Hi Prithwish, 

Thanks for your comment, I've made the modification and uploaded the new version under the same link: https://drupal.star.bnl.gov/STAR/presentations/WPCF-2022/Measurement-directed-flow-forward-and-backward-pseudorapidity-AuAu-collision

Thanks,
Xiaoyu

Dear Xiaoyu,
   Your slides look nice. Please do include one minor comment from my
side. I think saying "Issues addressed!" on the conclusion slides is a
bit out of context (for an internal STAR meeting this style is ok) . Can
you say something like "Challenges with forward v1 measurements" or
"Challenges & our approach"?

Best,
Prithwish
