High spatial frequency WFE maps for Roman OTA?

[mperrin]

@AldenJurling, a quick question for you: Is there a publicly available file for the Roman OTE high spatial frequency WFE?

Right now for the Roman WFI model in webbpsf, we have Zernike models for the low spatial frequencies, up to Z22. But no good information on the high spatial frequencies. As a proxy or placeholder, we use a version of the HST primary's high spatial frequencies, assuming that those are roughly representative. But of course that's wrong in detail, a completely different telescope from different polishing technologies decades ago.

This would be good to improve on in some future release, so I'm curious if you can help provide any pointers or contacts for pursuing this.

FYI @ojustino, @Skyhawk172

I will respond in email land where I can loop in the people who have more definitive answers than me, but are not on GitHub, then one of us can summarize here.

Just stumbled upon this open issue; Is there a high-spatial frequency for Roman available at this point in time @AldenJurling. I'm not sure what was communicated via email back then.

Thanks to our colleagues at GSFC, I've received an “as built PM" OPD file for Roman. I'll have to trim the edges, as recommended, and remove the lower-order Zernike terms we don't already model using the reference data (aka spreadsheet).

NOTE: this data is not yet public, so we'll have to hold on this update.
