The bonce mode was rung up vey high today (>1e-13m RMS in DARM). Worse yes, anything I tried to do just seemed to make it worse.
I tried both previous settings (see Keita's and Jenne's alogs below), but I was just ringing it up more.
The measured frequency today was 9.8320+-0.005Hz.
In the end it was so bad that the ITMY kept saturating, so I decided to leave the interferometer down for a feq hours.
Keita's elog on ITMY damping: 27680
Jenne's elog on ITMY damping: 29888
