J. Kissel, T. Shaffer

TJ has flipped the flag/magnets on H1 SUS ZM1 such that they now obey E1400316 as designed. I've also flipped the sign on the COILOUTF gains, such that make sense according to T1200015. Great!

But, sadly, in flipping the flags, the suspension is now rubbing, as shown by especially the Y to Y transfer function which now shows a second, unexpected resonance at 1.17 Hz (which is *not* the first L/P mode at 1.26 Hz, nor the first P/L mode at 1.68 Hz). Also, the P to P transfer function shows an abnormal change in the mid-resonances zero, and the (what should be the only) Y to Y resonance has shifted down in frequency.

Hurumph. 

When TJ came in he was mentioning that the OSEMs weren't well centered any more, and he later guesses that it's because the re-installed flags weren't as straight as he'd liked. Sounds like he's got an idea or two on how to free up the rubbing, so hopefully tomorrow's fix will be easy.
