ELOG Outline

• Aligned arms
• Took a bunch of photos of ITMY chamber. 
• Used Crystallaser to reverse trace POY beam path
• Realized real POY flashes were visible
• Tried adjusted POY steering to give us enough room to move SRM forward 3 in
• Not enough steering room
• Placed beam centering targets just before OM3 and after OM4, on far side of BS table
• Twisted SR2 by ~5 degrees
• Moved SRM laterally ~3 inches (beam had been hitting optic center, then suspension cage after SR2 twist)
• Moved SRM foward about 3 inches, adjusted angle for coarse retroreflection
• Measured distances between suspensions
• Tried running Gabriele's distance reconstruction code, results not looking so good; redundancy checks are off by ~1cm
• Started roughly repositioning OM1 and OM2 to get through beam targets
• Closed light doors
• ITMY pointing has gone bad, no green or IR resonance to be seen, still have IR and Green in Xarm, so TTs, BS are ok
