Hi Caroline and Maud,
Your comments have been incorporated into the manuscript. I will send another version of the proceedings around after lunch.

Hello Sebastiaan and Axel,
Thanks for sharing the proceeding. I rapidly went through and it reads well.
Could you include the folowing ackowledgement combine with the one sent by Caroline.
"This work has been supported by PEPR Origins, funded by France 2030 investment plan and operated by the French Research National Agency, grants No. ANR-22-EXOR-0002 and ANR-22-EXOR-0017."
Cheers
Maud

Hi Axel,
No problem, thanks for your fast reply and for taking care of the modifications! Somewhere in Section 4.1 and/or in Section 4.2.5 could you adequately mention post-AO control? I would prefer to leave it to you to suggest the wording, as I wouldn’t feel entirely comfortable doing so.
Also, I propose to modify the sentence just above section 5: "Ultimately, this shift towards data-driven prediction complements and builds upon foundational conventional
control techniques, such as the Kalman filter, which similarly utilize temporal state estimation to mitigate the
deterministic lag inherent in wavefront correction loops.80, 81", into:
* "Ultimately, this shift towards data-driven prediction complements and builds upon foundational conventional control techniques, such as the LQG regulator and its Kalman filter, which similarly utilize temporal state prediction to mitigate the deterministic lag inherent in wavefront correction loops.80, 81"
with reference 80 replaced by this one:
@article{Sinquin2020,
author = {Sinquin, Baptiste and Prengère, Léonard and Kulcsár, Caroline and Raynaud, Henri-François and Gendron, Eric and Osborn, James and Basden, Alastair and Conan, Jean-Marc and Bharmal, Nazim and Bardou, Lisa and Staykov, Lazar and Morris, Tim and Buey, Tristan and Chemla, Fanny and Cohen, Matthieu},
title = {On-sky results for adaptive optics control with data-driven models on low-order modes},
journal = {Monthly Notices of the Royal Astronomical Society},
volume = {498},
number = {3},
pages = {3228-3240},
year = {2020},
month = {11},
doi = {10.1093/mnras/staa2562}
}
And finally, the funding sentence for our activities in PCS:
"This work has been supported by PEPR Origins-UPCAO project, funded by the French Research National Agency (France 2030 investment plan), grant No. ANR-22-EXOR-0017."
Thanks again and I wish you all a nice summer time,
Caroline

Hi Caroline,
I believe Sebastiaan was not aware of your team's participation in WP2.3, which is entirely my fault. I did not pay enough attention to the author list.
Of course this work is more than valuable to PCS and I hope those discussions will resume after the summer break :-) .
I add you all in the author list.
Please let us know if you have any other comments on the proceedings,
Sorry again for the oversight,
Best,
Axel

Objet : RE: [Pcs-wp2] Draft of SPIE proceeding
Dear Sebastiaan,
Aya Harkat, Nicolas Galland and myself have worked with Henri-François on the data provided by Axel and Arthur in the framework of WP2, as I had proposed at one of these meetings to study the potential of predictive control for post-AO residuals. Could you please add us three in the authors' list?
Thank you,
Caroline
PS: I'm currently at the EAOSS (summer school) and could not read your email until this evening.

Objet : [Pcs-wp2] Draft of SPIE proceeding
Dear all,
Please find the attached SPIE proceeding for our work in WP2. Currently, authorship is based on either participation in the zoom meetings of WP2 or making contributions to the work in WP2.
I will submit this tomorrow afternoon at 5 PM because I will away on vacation after that.
Met vriendelijke groet / With kind regards,
Dr. Sebastiaan Haffert
