MitchR, JimW BSC2 was unlocked and balanced this morning, mostly problem-free (except for a CPS power cable that had come unplugged) requiring only small changes to the BSC's trim mass on both stages. Locked/unlocked shifts are <500 cts for St1 and <1000 for St2. SUS's C3 cover and optic shields were carefully removed and are sitting on the nearby tables if needed (please notify SEI people before re-installing these). The ISI was left floating  for testing, while we have the window.
