These plots show the offsets between P1/P2/P3 and the interferometric channel.
The values in the plots marked as "from header" (black dots) are retrieved from the headers of the P2VM HIERARCH ESO Px OFFSET (they are calculated by the instrument)
The values in the plots marked as "recalculated" (red dots and green dots) are recalculated on the WAVE raw files using the pipeline (red dots) or Antoine Merand's python script (green dots)
