The new highest vertical (a.k.a "bounce") and roll mode frequencies for H1SUSETMX, measured at vacuum using driven excitations a.la. methods described in LHO aLOGs 41488 and 40098 are as follows:
    
    V4   9.703 +/- 0.005 Hz

    R4  13.757 +/- 0.005 Hz
I'll update the uncertainty estimate later, once I can download the excited data I mention below.

I've driven up the modes at two times (listed below) in order to gather an estimate of the Q, which I'll do again similarly to the aLOGs cited above once I get three.

             Exc Start                Exc Stop
Trial 1      Aug 28 2018 23:50 UTC    Aug 29 2018 00:02:00   (stopped with 10 sec ramp)
Trial 2      Aug 29 2018 01:05 UTC    Aug 29 2018 01:15:00   (stopped suddenly but turning off TEST output)
I'll want to get one more excitation time (plus an hour of ring-down time data). I'll look for a good target of opportunity in the next few days. It''s already obvious from watching the modes ring down in the sensor ASDs that the Qs will be in the 1000s, unlike ETMY which was unusually low (in the mid-100s) and split.

The template for measuring the ASDs of sensors lives here:
