During the September run we found that we need to fully cover distortion so that pfi&lt;-&gt;mcs transform is round trip.</p> INSTRM-1402

update the transforms and make the pfi <--> mcs transforms exactly round trip

As I found something with the data, we are talking about calculation with her now, which will take a time.</p> <p>I updated the code to ticket branch. When I ran the code, the difference between the original PFI position and round-tripped PFI position is several um (at most) in the case of EL=90, no ADC movement, and ~50um (at most) in the other cases. The error in other cases comes from pfi-&gt;mcs transformation. (At present, error of a half pixel remains.) I need to think about better solution, but if it can be done another ticket, I'll merge this branch for now.</p> <p>Following conversations at the commissioning telecon on 10-11 Nov 2021, I merged the branch to master and close this. Analysis with Top-level utilities will be done separately.</p> Development Rank 0|zzsgd0: Sprint PreEngRun4 EngRun3Cleanup Story Points 4.0
