Dear Stephen, Sidney, and Damian,

Thank you for responding to the reviews of your manuscript from Klaudia Kuiper, Daniel Wielandt, and Trevor Ireland. Your response to the reviews is thorough, and it appears that you have or will incorporate all of the requested changes to the manuscript. I therefore recommend that this manuscript be published subject to the revisions you describe in the response to reviews. I look forward to reading your revised manuscript.

Best,

Dear Stephen, Sidney, and Damian,

Thank you for submitting your manuscript revisions. Your manuscript is suitable for publication in Geochronology, pending some technical corrections outlined below.

Lines 32-35: With the extended parenthetical note, I now find this sentence hard to read. I recommend breaking this up into two sentences.
Line 65: If it's possible, can a reference be provided for the nonlinearity < 1 ppm?
Line 267: Just a heads up, Klaudia Kuiper's review was also solicited, she just selected a different type of comment upload. You may wish to revise these acknowledgements to reflect that.
Figure 7: The line/shaded area for shot noise is really hard to distinguish from the other very faded linear fits to each dataset. I recommend making this a different, bolder color.
Figure 8 caption: Contamination is misspelled.
Figure A3 and A4 captions: A period is needed at the end of the final sentence.
Figure A5, A6, and A7 captions: It would be helpful to state the ATONA integration time in the figure caption itself. Even though this information is in the figure title, the title is small and easy to miss. Also, the parentheses need to be closed after 'see section 3.1' in each of these captions.

Best,

Marissa Tremblay

I agree with Marissa's assessment.

As regards acknowledging the reviewers, if you look at some final published articles you will see that a statement of the reviewers is added by Copernicus at the end during the pagesetting. That is, if you want to particularly thank certain reviewers, certainly that can be in the acknowledgements, but they'll already be named in the final version anyway.
