Dear Prithwish,

     Thanks for the comments. The updated version can be found at:

Hi Shengli,
  The new version looks good, please consider a couple of additional
comments.

We should either say "A weak system dependence of v3" or "A system
independence of v3"

underlined physics --> underlying physics

This statement about similar vn at RHIC and LHC is valid for the same
centrality bin right ?
(Like what is shown in https://arxiv.org/pdf/1904.10415.pdf )

Then maybe we should clearly mention it?

How about:
"Similar to large system, vn in p+Au at RHIC has also been found to be
similar to the same in p+Pb at the LHC."
-->
  "Similar to large systems, at comparable centralities, vn in p+Au at
RHIC has also been found to be similar to the same in p+Pb at the LHC"

Best,
Prithwish
