Hi Sebastiaan,

The work I've mentioned is this one:

\inproceedings{Harkat2026, title = {{Predictive control for the compensation of NCPAs measured with SPHERE/ZELDA}}, author = Harkat, Aya and Raynaud, Henri-Fran\c{c}ois and Galland, Nicolas and Vigan, Arthur and Potier, Axel and N'Diaye, Mamadou and Dohlen, Kjetil and Kulcs'ar, Caroline}, year = 2026, month = {June}, booktitle = {SPIE Conference on Astronomical Telescopes and Instrumenation}, editor = { Kathryn J. Jackson, Dirk Schmidt, Elise Vernet }, organization = {SPIE} }

Thank you, Caroline

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. ________________________________ De : haffert@strw.leidenuniv.nl haffert@strw.leidenuniv.nl Envoyé : jeudi 16 juillet 2026 14:02 À : pcs-wp2@strw.leidenuniv.nl pcs-wp2@strw.leidenuniv.nl 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.

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 ________________________________ De : Axel Potier axel.potier@obspm.fr Envoyé : jeudi 16 juillet 2026 23:16 À : Caroline KULCSAR caroline.kulcsar@institutoptique.fr Cc : Sebastiaan Haffert haffert@strw.leidenuniv.nl; pcs-wp2@strw.leidenuniv.nl pcs-wp2@strw.leidenuniv.nl Objet : Re: [SPAM] [Pcs-wp2] Re: Draft of SPIE proceeding

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
