I tried a bit to poke the PRM to convince it to do better with PRMI, but it seems that things are off enough (even after having watched guardian do MICH_FRINGES when I hand-selected MICH) that PRMI ASC can't do enough. So, I've requested initial alignment.
Initial alignment went smoothly, with no interventions.
It seems like the bottom scope on the front wall center TV is frozen. Daytime operator, please restart it.
Requested NomLowNoise. DRMI caught quickly. As folks have been talking about in the control room the last few weeks, we should look in to why PRM in particular seems to move between locks more recently than it used to. I'm not yet sure what exactly to trend, but maybe an operator can have a look at the PRM top mass osems at the start of locking for the last few lock attempts, versus the top mass osems after initial alignment completes, and maybe also versus after DRMI ASC is offloaded.
DRMI ASC did bad things and got wobbly, but then seems to have recovered itself.
Things are overall going well (we're just about to power up), so I'm going to sign out for lunch. I'll try to check back in later.
Conclusion from this lock: As soon as the analysis pipelines have suffiicient double coincident data, we (I) should go back to giving more time for commissioing TJ's IFO Manager, that will know when it is time to do an initial alignment before continuing to attempt locking.
