Having finished the BSC-ISI drives early and with an hour to spare, I spent ~30 minutes tuning up templates to find if other QUADs than ETMY have the same kind of spurious high frequency dynamics on their UIM stage; a part of the approved end-of-run close-out measurements for the CAL group (see JRPC page). 

ETMY was confirmed to have far-from-simple-f^(-6)-roll-off in UIM actuation to test mass response above 100 Hz back in ER10 (see LHO aLOG 31603), so I was copying those templates.
Unfortunately, I was only able to complete one frequency band of broad-band injections for ETMX, and then I broke the lock on the second band trying to get more SNR.

The data I did get lives here:
/ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Measurements/FullIFOActuatorTFs/2017-08-06/
    2017-08-06_H1SUSETMX_L1_PCAL2DARM_HFDynamicsTest_100-250Hz.xml
    2017-08-06_H1SUSETMX_L1_iEXC2DARM_HFDynamicsTest_100-250Hz.xml
which was enough to show, indeed, some nasty resonant feature in UIM actuation in that band.

In the fullness of time, I'll process, plot, and post this data once I get the rest of the suite as I'd had before, but processing the broad-band ISI injections is a priority at the moment.

Note: taking this data required me to briefly turn off all calibration lines on PCALX (333.9, 1083.3, and the roaming line which was at 2001.3 at the time of lock loss). However, all was restored after the lock loss, and the lines are back on wit the roaming line driving 2001.3 again.
