ITMX OpLev sum glitching every 6 seconds
I was looking at the time series for OpLevs, when I came across the curious case of ITMX glitching every 6 seconds (see attached figure). Not sure why it would be doing this, but certainly should be investigated/fixed. As far as I can tell, it is the only one of the OpLevs doing this. I went backwards in time to see when this started; it's been around since at least the start of ER10.
