Rough summary of today's progress:

• IMC locked, reasonably aligned. (Only have MC2 trans reference, no WFS)
  • FSS Slow lock threshold got lowered to 1k MC2 trans
  • Autolocker doesn't really work, though I made some modifcations to it that reflect the manual locking that works
• TTs, PRMI optics moved around until AS and REFL spots looked good. 
  • Small flashes visible in TRY
  • ND filter on Y transmon QPD removed, since we have so little light
• Y arm was not locked, but this was deemed suitable to proceed
• Heavy doors taken off ETMX and ITMX chambers, light doors put on.
• Went into ETMX chamber, poked around, took a bunch of pictures (Gautam is uploading has uploaded to picasa (foteee account), the two best ones of the stand-offs on either side are attached, although I guess we can't really conclude anything from these except that on the side with the OSEM, there seems to be a few extra stray bits of epoxy residue...)
• Removed ETMX side OSEM to get a picture of that side of optic (it is currently off, ETMX watchdog shutdown for now...)
• Checked that table is level with clean spirit level (it was to within the resolution of the spirit level which is quoted as 0.42mm/m)

I didn't really see anything out of the ordinary on the ETMX suspension. Earthquake stops had clearance, OSEMS were secure, no visible glue degredation on face magnets. Inspection with green LED flashlight didn't reveal any obscene dirtieness on either face, just a few particles here and there. The top of the opic barrel unsurprisingly has a good amount of particulate. The wire grooves are way too small to resolve anything at this point, other than that they exist.

The suspension footprint is already marked, tomorrow we can move the suspension closer to the door to get an even closer look at it, before removing it from the chamber.
