Full alignment of the IFO was recovered. The arms were locked with the green beams first, and then locked with the IR.
In order to use the ASS with lower power, C1:LSC-OUTPUT_MTRX_9_6 and C1:LSC-OUTPUT_MTRX_10_7 were reduced to 0.05.
This compensates the gain imbalance between TRX/Y siganls and the A2L component in the arm feedback signals.
Despite the IFO was aligned, we don't touch the OPLEVs and green beams to the vented IFO.
