IO alignment is complete, until final check, and until after a fix for IM2 and IM4:

• IMC input beam alignment checked on MC1-MC2 path - OK
• IMC flashed - alignments recorded (posted later)
• IMC trans alignment checked - OK with IM alignment sliders zeroed, except IM2, which has a +2000 slider value
• PRM transmitted beam alignment was as expected - high on that iris
• the beam on PRM trans is high due to a -4000-ish pitch misalignment of IM4 when the alignment slider is set to zero
• hardware adjustment will be used to correct IM4 pitch pointing
• IM2 suspension wire needs to be backed off from a metal part
• two IRIS markers to be installed in HAM2
• all temporary hardware to be removed tomorrow for ISI rebalancing

Other IO changes to the HAM2 payload:

• ECR to swap IO dog clamps to SUS dog clamps on IMs submitted yesterday (only IM4 at LHO, all IMs at LLO, and plans changed accordingly for 3IFO)
• due to the weight difference in the dog clamps, it would be advisable to do before rebalancing, though ECR is not yet approved
• SUS dog clamps to be installed are D1100641V2 type 03, and D1100641V2 type 02
