WHAM4

The HAM4 level balance was fine.  There is one horizontal locker that shifts 1750counts (our spec is 1600) but all others are less than a few 100.  Adjusting the locker to correct this will only change the locked position; the floating position will not change.  See the first attached plot for the shift from locked (whence alignment has been done) at the start of these trends, to the unlocked position at the end of the traces.  The Rz is the likely most significant at 15urads, Rx is 10urads with Ry at 3urads.

WHAM5

HAM5 required some mass shifting to balance the level.  HAM5 H1 is a bit worse than HAM4 with a shift of 2500counts.  See the second attached for the cartesian shifts.  Note Rz is 30urads.
