Apparent alignment shift in FC1 and FC2 due to satamp swap
The satamps for FC1 and FC2 were swapped out today as part of ECR E2400330, and a new compensation filter was installed in OSEMINF, so it will look like we have had a change in the alignment of the FCs, but this isn't a real change(FC1, FC2).
