Arms and PRC hold well, powers are within normal ranges. (TR[X,Y] >.9, POP110I > 400)
Then, Jenne took over, worked some alignment magic, and did the hard part of getting the Yarm locked and ASS'd.
Green no longer locks to 00 on the Y-arm, and the X-arm green transmission isn't the best despite PZT fiddling (~.6). Also, when green is locked to the Xarm, I see a distinct circular spot on the GTRY camera, with Y green and PSL green shutters closed.
While Jenne used Yarm ASS successfully, when I run it now, it slowly pushes things out of alignment, and two of the traces (YARM_ETM_YAW_L_DEMOD_I_OUTPUT, and the same for ITM) have a reasonable constant offset that doesn't move away.
