H2 SUS ETMY M0/R0 Diagonalization
Diagonalization measurements were run on the H2 ETMY M0 & R0 top masses yesterday.  Results are attached.  The results show ideal isolation for the two DoFs on both masses.  Each DoF on both masses is at least 20dB isolated from the other OSEMs, which is well above tolerance.

M0 Yaw:
25ct amplitude at 1.3Hz
21dB isolation

M0 Vert:
1000ct amp. at 2.2Hz
25dB isolation

R0 Yaw:
25ct amplitude at 1.3Hz
24dB isolation

R0 Vert:
1000ct amp. at 2.2Hz
23dB isolation
