After running dither alignment for all mirrors, all oplevs were recentered. (Except ETMY, since we did that earlier today.)
Looking at Koji's template for OSEM signals, the ITMX UL sensor noise floor seems more in line with the LL sensor, though there continues to be more noise than in other mirrors.
Trending the sensor signals over the past 7 days, Koji's measurement looks to have been taken during a time when the UL sensor voltage had jumped down. Did someone squish the satellite box cable? I have not done so.
I think that the step right at the end is due to a new POS offset of -2k counts, which I think Koji put into place earlier today.
