Today I have checked the BS IM status.

As reported by Terrence in klog7705, the TFs for Longitudinal, Transverse and Yaw show an unusual behaviour, and since the IM Pitch, Vertical and Roll seem to be healthy, I don't think there is something rubbing. See figure 1 to 6.

There must be something wrong with the IM horizontal power coil driver or the horizontal satellite amplifier. In fact by applying an offset at IM Pitch, it can be seen the coupling to the other DoF (And this means the IM is not touching). See figure 7.

We will check the high-low power coil drivers and satellite amplifiers tomorrow.
