H2 SUS ETMY M0/R0 Diagonalization
Diagonalization measurement results for H2SUSETMY M0 & R0 are attached. 

For M0, the Vertical DoF is at least 22dB isolated from the other OSEMs at 2.25Hz, which is excellent.  The M0 Yaw DoF,however, appears to be highly coupled to the F1 and SD OSEMs at 1.3Hz (the Yaw DoF consists of the F2 & F3 OSEMs) - the M0 TOP mass might need some adjustments to decouple Yaw.

For R0, the Vertical DoF is roughly 10-12 dB isolated from the other OSEMs - on the cusp of tolerance.  The Yaw DoF is about ~15dB isolated, which is good.
