Hello Nihar,

Thank you for your comments.  I have adjusted the statements you mentioned.

L16: v_{2}^{ch jet} -> v_{2}^{jet}  [you don't need to mention "ch jet"
as you have mentioned using "charged jet" in that sentence, this is
fine]

I would like to keep this as v_{2}^{ch jet}, both to stay consistent with the ALICE result (1509.07334.pdf (arxiv.org)) and because I may in the future measure v_{2}^{jet} using full jets.

Cheers,

Tristan

Hello Tristan,

Please find my following suggestions.

L11: "…observables, including dihadron correlations and dijet
asymmetry." -> "…observables, such as dihadron correlations, dijet
asymmetry, etc.

"Another approach to  measure jet quenching effects is to determine the
anisotropy of the distribution of jets with respect to the event plane."
I would suggest to modify your sentence like
"Nevertheless, the path length dependence of jet quenching can be
studied by measuring the anisotropy of the jet distributions with
respect to the event plane in heavy-ion collisions."
Then your next sentence "Due to the approximately elliptical …" comes
coherently in a flow.

L16: v_{2}^{ch jet} -> v_{2}^{jet}  [you don't need to mention "ch jet"
as you have mentioned using "charged jet" in that sentence, this is
fine]

L17: "Zr+Zr systems."-> "Zr+Zr collision systems."

L19-21:"The EPD enables this measurement by allowing the event plane to
be determined in the forward region, creating a gap in rapidity from
where jets are found which  reduces autocorrelation effects with respect
to the event plane determination."
-> I would rephrase this.  "The EPD enables the determination of the
event plane in the forward rapidity, whereas jets are measured at the
mid-rapidity that mitigates the autocorrelation to the jet measurement
in STAR."

cheers
