Got the full TF this morning on HAM4.  As expected and seen on the other platforms, the HEPI features seen in the ISI TF from 10-40hz are lower in Freq & Q--likely from the floating HEPI itself.  And now with the HEPI loops at 2hz ugf rather than 5, that nasty zero near 6hz becomes much less nasty--see attached.  This shows the local to local TF of the ISI Actuators to the CPS.  The H3 sensor on the HAM ISI aligns with the long axis of the HEPI crossbeam.  In the Cartesian basis, this is the Y axis for HAMs 2 & 3 and the X axis for HAMs 4--6.
