Previous transfer functions of SR2 showed what looked to be cross coupling between Yaw and Roll at approximately 0.75Hz. 

   After checking (1) the BOSEM centering and alignment, (2) the alignment of the BOSEM flags and flag mounts, (3) the level of the Upper Mass and the Tablecloth, and (4) verifying there were no mechanical interferences, we re-ran the TFs for H1-SR3.

   The plots still show a Yaw peak at 0.73Hz. We ran DTT and did not see the same peak in the Yaw DOF. There was good coherence at this frequency. Jeff K. looked at the plots; concluding this peak was probably environmental noise, gave his consent that this suspension is ready for the glass mass installation. 

   The plots for the last round of transfer functions are posted beflow.
