While digging through the details, I found that the CAL-CS was compensating and old value for the high frequency, ~3.2 kHz, pole in the ESD low-voltage low-noise driver that results from the PI summing node.
What was in place: 3323.421 Hz -- comes from Evan updating the number for ETMX based on the mean of measured poles from 07 June 2016 of the ETMY driver (see LHO aLOG 44469 for when the filter was last updated, which cites the measurement in LHO aLOG 27619)
What is no in place: 3226.75 Hz -- comes from the mean of the ETMX driver poles measured on 04 February 2019 shown in the "summing node" column of LHO aLOG 46773.

This is a small change (0.3% / 0.5 deg at 1 kHz in the TST actuator), bit it was an inconsistent detail that I'd rather reconcile in a see of confusion about small numbers.

We'll be updating the remaining calibration later this afternoon, so one should just consider this a part of that.
