The transfer functions that Jeff G started last night, have completed, and they are stored and committed to the repo, under
${SusSVN}/sus/trunk/BSFM/H2/FMY/SAGM1/Data/2012-03-12_H2SUSFMY_M1_0p01to50Hz_all_DoFs.mat

Attached are the results, plotted using,
${SusSVN}/sus/trunk/BSFM/Common/MatlabTools/plotBSFM_matlabtfs.m

I found that, regrettably, either
- FMY is still rubbing; in fact, worse than before (See pg 2)
- The watchdog tripped throughout the entire measurement (or at least the low frequency end) (See pg 1, 5, 6)
- The coil driver whitening/BIO settings (which I'm not sure were checked to be set properly after Richard was finished playing) were not set properly for the "normal" drive for a transfer function -- this could be the cause of watchdog tripping / bad SNR
- The OSEMs are totally broken. (See pg 3)
- The mechanics of FMY are [damaged/poorly suspended/out of alignment].

I don't *what* the heck's going on with vertical, but I'm pretty sure the other DOFs (L, P, Y) are watchdog trips / no signal drive; T looks like rubbing.

I've later confirmed that the H2:SUS-FMY_BIO_M1_STATEREQ state request channel was to 0 (see .png attachment) BBUUTT -- I'm not exactly sure if this disallows excitation, or puts the analog switches in a weird state. The digital compensation filters were turned on in the appropriate state...

Taking DTT TFs now...
