Jim reported yesterday that the cold restart of the ISI from the long Tuesday shutdown led to a thermal sag causing an increase vertical drive in turn causing a yaw...Not sure why the horizontal loops would not keep the yaw at minimum unless the heating is also impacting Stage0.  Attached are 48 hours of the ITMY vertical drives, one horizontal drive and the OpLev signals.

Okay, based on the horizontal drive, the loop is dealing with the yaw but of course relative to Stage0.  Is HEPI or Stage0 the source of the actual Yaw or a secondary affect...not sure I can reconcile that.  Also, while V1 and V2 show pretty flatline drive before and since the isolation cycle yesterday afternoon, V3 and the H2 show a continuing trend that was present before the reisolation.
