Checking SUS TFs for rubbing

[ Matt, TJ ]

We looked at the transfer functions of the suspensions of the Test Masses, SR3 and PRM (top stage of each), to see if we could see signs of rubbing. This is a limited number of transfer functions; however, it does seem like there is some peak shifting in the ITMY-P.

PRM LPY, and BS LPY. I had to turn off the BS OpLev damping, which is mentioned in the Jeff K TF instructions wiki.
