Use the provided (ra, dec, pa) pointing to generate approximate ra, dec for the fibers. If none provided, set all ra/dec to NaN. In any case, set all pfi positions to NaN.</p> <p>ra/dec/pa might be fuzzed to avoid information leakage, but that would be done by the ICC caller.</p> INSTRM-1418

Add `getSunssPfsConfig(ra, dec, pa)` function

But we do have the angle of SuNSS relative to the telescope calibrated, right? <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=yuki.moritani" class="user-hover" rel="yuki.moritani">yuki.moritani</a>?</p> <p>Well, I think Jim's document (page 8 of AligningSunssV4.pdf) answers  the question?</p> <p>Thanks for the pointer. So the x-y shift using the set screws has been applied? In which case the telescope boresight falls on the center fiber, and from there N is 4.1 degrees East of fiber 1 (6.7deg from the truss angle minus the 2.6deg measured calibration for the ferrule seating, etc.). Right? With 7 fibers along the 60deg edge that seems a good match with the figure...</p> <p>Yes, one adjustment was applied, and we checked the adjustment.</p> <p><a href="https://pfs.ipmu.jp/internal/SlackArchive/Full/commissioning.html" class="external-link" rel="nofollow">https://pfs.ipmu.jp/internal/SlackArchive/Full/commissioning.html</a></p> <p>(See a few conversations from "rhl Sat 2021-04-03 01:58PM")  We were almost there. Further analysis is needed if we apply the second alignment.</p> <p>Yes.. 4.1 degree sounds correct.</p> <p> </p> Blocks INSTRM-1422 Development Rank 0|02qpjd:00xznup2d1
