Mid Shift Summary: H1 Locked! (But Some ISIs in LO Gain) :(

After the alignment tweaking with Jenne, and getting through PRM, I continued with the Initial Alignment.  The Dark Michelson came up on its own fairly well aligned and I only barely touched it.

After the IA, attempted locking.  First attempt was on an ugly DRMI mode.  Second Attempt locked DRMI within 10-15min.  Proceeded through Guardian States.  First hitch was at ENGAGING ISS 2ND LOOP.  Ended up having to Engage by hand (via Kiwamu's alog); this was scary as it's hard to engage when output is close to zero---had a big glitch when I engaged, but it rode through (yay!).

Finally made it to NOMINAL LOW NOISE with range around 80Mpc (but had a few DIFFS on SDF).  The Diffs were:

Input Pointing Diffs:  

Some ISIs in GS13 LO Gain Mode Diffs for HAM2, HAM5, ITMx

Now working on getting H1 back UP (& going to have dinner soon).

I meant to attach snapshots of the SDF diffs I observed last night, but forgot to get to that (wrote alog on my laptop and saved snapshots on ops workstation Desktop).  

Mainly thought the input pointing changes were worth noting, since that was a noticeable/big change to H1.

Will post when I'm back on shift tonight.

Here (attached) are differences from SDF I noted in the main entry.
