Lockloss at 21:15UTC from In-lock charge Measurements
We tried the in-lock charge measurements but forgot about the New-DARM configuration so caused a lockloss in the SWAP_TO_ITMX state.

It seems also that only ETMY was ever moved during the part of the test that did run (I'd expect everything but ETMX measured, because the last one requires switching control to the other TM which caused lock loss). In the measurement last week, it seems excitation was applied on all masses as it should be. Attached are plots from this week and last week.

I've attached the plots for ETMY, since that's the only one that had the excitations this last week.
