confirm that mapping from cobra to sm1-3 fibers is correct

Data has been taken in the last september run to check the mapping from cobra to sm1 fibers.
I already analyzed it at the summit and it looked fine as far as I remember.
I just need to confirm this result and declare this no longer a problem.

Data has been taken again (2022-11-17, iic_sequence_id=18555), with sm1 and sm3, I'll post the results here.
