Summary--Changing Guardian code to not switch the GS13 Gains during the Isolation removes the RZ twist seen previously.

See attached, At T=1 the guardian zeros the CPS offset and Channel6, the GS13 SWSTAT switches the GS13s to low gain w/o whitening.  This is a coding error we are fixing, it should be going to high gain w/o whitening.  On channel9 at T=1 the DAMP path glitches which is seen on the RZ_INMON. After the Z loop closes, which glitches, the RZ comes on shortly thereafter and the big excursion on RZ_OUT16 swings the table.  Fortunately, the WFS loops now keeps the DRMI riding through the switch.  At T=2, the Isolation is taken down, evidenced by the OUT16s going quiet and the INMONs going noisy.  Immediately I switch the GS13 to whitened low gain and again this glitches the damping out and the ISO INMONs.  At T=3, Guardian does the isolation this time with switching the GS13s and no glitches are seen on the ISO INMONs nor OUT16s, everyone is happy.  I don't know from what the VHF spikes seen on the GS13INF (Channel7, lower right) originate but they do correlate to a transition to reduced inertial sensor noise... maybe it is the complettion of the Isolation and the BOOST filters.  At T=4, the guardian test is repeated with similar results.
