After ISCTEY rearrangement I looked at the WFS sensing, but it didn't behave well. Disappointing.
The difference between before and now, apart from the table rearrangement that shouldn't have caused much impact on the sensing, is the ITMY beam position. Maybe the WFS signal is dependent on the beam position?
Tomorrow I'll try to find a good set of centering offsets for the current beam location, as the alignment now is supposed to be good.
Could we have a ghost beam problem?
