Earlier this evening I kept the arm locked, but we unsuccess full in generating a proper spectrum. This was because the RefCav kept dropping lock every ~10 min or so, see the first attachement of the StripTool.

I did manage to get a spectrum (only 8 ave in a <10 min stretch), and it is nice to see the noise above 1 Hz dropping due to the work on the RefCav. In the other hand we have not made anyhead way at the lower frequencies.

To that end I tried to engage the Trilliums on the ISI's, which I did but then got trumped by the 10 min lock treches. I was worried to keep the ISI running with the Trilliums overnight, so I reverted back to running with the L4C's overnight.

When writing this entry, the cavity is still locked, but has the ~10 min lock loss after which itself brings into lock. This is sort of an hiddious autolocker:)
