We were able to collect the entire suite of calibration measurements (sensing function suite and each of the three actuation stage suites) in 
    - the current nominal configuration (i.e. Spot moved back to "July" positions, with a digitally requested SRCL offset; see LHO aLOGs 51592 and 51440), and 
    - in the proposed new actuator configuration (i.e. PUM L2A filters back on, and with the UIM longitudinal control boosted below 0.3 Hz; see 51717 and 51709).

Recall that we plan to update the front-end calibration next week Monday (Sep 9 2019), and in doing so, adopt the newest, latest, bestest configuration tested today and thus create a new epoch of O3. 
These measurements will inform and complement that model and its uncertainty nicely. 
Also, FYI, that update will resolve the discrepancy between front-end and GDS computed BNS ranges on the summary pages (not the reason we're doing it, but a nice side benefit).

Analysis and more details to come!
