Thanks to Keita's work on ETMX Damping (alog 16895) and L2P (16968), we are now locking ALS DIFF with no oplev damping on either ETM.  Attached are spectra from all four stages of both quads, in both cases the ETMY oplev damping was off, for ETMX the solid lines are the old configuration with oplev damping on, the dashed lines are the new configuration described in Keita's alog with the OpLev damping off.
