The corner isi sensor correction was turned on at 20:45 PT and will be running overnight in order to evaluate the possible improvements from the new HAM3 CPS. It had been left off to avoid noise reinjection from people working in the LVEA, but should be ok to have on during the weekend. Having the sensor correction ON for some time will allow to compare the ISI spectra with last year's, before the CPS change, in the same control state.

A quick check of the HAM2-3 (X, Y, Z) was done before / after the change to verify there is no issues (fig 1 - blue is before, red is after). The IMC stayed locked during this transition (control signal in fig 2 - blue is before, red is after).
