OPS Monday owl midshift update
We had a lockloss at 07:57, relocking was mostly automated I only had to intervene to help Xarms PLL lock. I had to hold in OMC_WHITENING for about 1.5 hours for the violins to damp. Back in NLN and Observing as of 11:00 UTC.

I ramped up the gains for many of the rung up modes (see screenshot of the DARM spectra for 500Hz and kHz modes), however it still needed around 1-2hrs of before DCPD counts were below 500K counts (for Nominal Low Noise state). All gains are currently set to their nominal values.
