As was suggested a couple of days ago (28480), we recentered the POP QPDs by moving two pico motors in HAM3. The centering was done when the interferometer was fully locked with a 2W PSL and with the full ASCs engaged (except for PRC1 which uses a POP QPD).

Here are the pulse counts that we introduced to the pico-motors (pico A or controller 3) today.

• Drive 5 (POP A): (x, y) = (-2979, 3258)
• Drive 6 (POP B): (x, y) = (-2729, -4742)

After pico-motoring, we took out the offset in POP_A(B)_PIT(YAW)_OFFSET and re-closed PRC1 without an issue.
