(Keita, Stefan)

We noticed that the feed-back gains of RM2 were the opposite of RM1. So went through all 6 tip-tilts that we have at LHO, and determined their magnet polarity:

As viewed from behind (incl magnetic pole facing backward):
Default:
  UL: N, UR: S
  LL: S, LR: N
The following serial numbers are conform with that: 009 (bad wire), 002, 033, 004, 022 (RM1)

Serial number 024 (RM2) is different:
  UL: S, UR: N
  LL: N, LR: S

For now we flipped the digital coil gains of RM2 to account for that.
