Redisual Excitation Leftover from Headless Calibration Sweeps -- now cleared
J. Kissel

As indicated in LHO:69065, we lost lock in the middle of a headless run of the calibration sweeps. What we didn't see until this morning was Louis' instruction that we need to clear test points after we ctrl+C out of a failed headless run of the sweeps (LHO:69072). As such, an unintented, 5.6 Hz ETMX UIM excitation had been running since yesterday afternoon's lock loss. 5.6 Hz merely because that's where the ETMX EXC sweep was at the point of lock loss.

I've now cleared that test point at of 2023-04-27 ~17:22 UTC.

I'll work with the pydarm measure authors to make sure we have a graceful exit of headless operation if/when we have a lock loss in the middle of the measurement.
