ETMx TFs again
Starting another set of M0/R0 TFs on ETMx, this time with the new M0F1 OSEM and with damped TFs as well.
Checked at 8:40 am: undamped TFs done, damped TFs just started - will be going the rest of the day.
TFs done by 5:48 pm
Undamped:

Plots pending.
Plots are attached. All the undamped plots look good, with the usual caveat that some of the R0 pitch frequencies are high due to the cabling. The damping on pitch is a bit high - we need to update the filters to correspond to H1. I'll do spectra next, and then revisit filters and damped TFs as time permits.
Here are spectra. I had to modify the plotquad_spectra.m script to support X1 - I hope I didn't break anything for X2. The Euler basis signals on X1 have different names (H1:SUS-ETMY_L1_DAMP_L_INMON etc vs. X1:SUS-QUAD_L1_WIT_LMON etc) and aren't logged to the DAQ, so I changed the names and commented them out. There are currently no OSEMs plugged in at the lower levels, so that will do for now.
