Looking into (1) from 84462.

Before this vent, although the cable pinouts were flipped for both RMs, the phase for the TFs were at 0. Now that the cables have been flipped (fixed), we are seeing that the closeout transfer functions that I took 84498 are showing that the phase for the RMs is now flipped, at 180. Additionally, both RMs are still needing the damping sign to be +1, instead of the usual -1.

Since there does still seem to be a sign issue somewhere in the sensor chain for RM2, we would have expected the 'after' transfer function phases to differ between RM1 and RM2, so it's strange that they both have switched over to 180.

I've attached the transfer functions for RM1 and RM2 comparing the after vent measurements to the last measurements we had done for them with damping loops off, which was in 2022.
