Some coherence with OAF-CAL_MICH goes away with the servo OFF, very little coherence seen in PRCL or SRCL

DRMI was locked for 9 hours until ~1527utc 30 Jan.  POPAIR_B_RF18_I_MON was at 300 when lock was lost.

Measurement started at 0700utc for HEPI Pump Servo On data; Measurement here at 220015 during a DRMI stretch for Pump Servo Off data.  Lots of activity during this time so a quieter stretch with servo off would be good to have.

On the attachment you see plenty of coherence between 10 & 100mHz that pretty much goes away when the servo is turned off.

Also attached is the amplitudes of the Mich and the Pump Pressure and the STS floor seismometer.  Input motion looks pretty similar but there have been activities in the LVEA today.  The weird nature of the Mich signal at higher frequencies may indicate I'm too close to the lock loss or something.  Will repeat this when the DRMI is quiet.
