Weekly In-Lock SUS Charge Measurements
Ran the data for the In Lock SUS Charge Measurements that ran this morning. Like Camilla said (76895), the excitations only worked for the ETMs, so although I am attaching all four plots, note that the last plot point for the ITMs is March 13th (ETMX, ETMY, ITMX, ITMY).

Adding these measurement results also calculated with new scripts. As far as I can see, similar trends show up with the caveat that signs of variables are sometimes different. By the way this makes me wonder a bit. We'd assumed that ETMX got charged up during the break, but the absolute value of beta and beta2 (which determine linear force component strength - see eq.3 in T1700446) for ETMX in last two measurements go down in both old and new calculation. Isn't it the opposite of what we'd expect?
