Mid Shift Status: Pesky ITMy BOUNCE Mode

As we tried to go up to LOWNOISE ESD ETMY earlier, we could clearly see several lines on the DARM spectra and these were traced to a BOUNCE mode (ITMy to be exact).  Stefan has been trying various gain changes & filter changes, but everything seemed to just excite the mode more.  

Right now we're turning off Locking to let the system quiet down.  Then we'll get back at it.
