I trended the DARM offset (via checking the fringe offset OMC-READOUT_X0_OFFSET) and the circulating powers in 04 a on Jan 14th and on March 16th post-vent.

The offset and circulating powers have not changed appreciably. The first image is 04a and the second this past Saturday. In both cases the contrast defect was set to give 40mA on DCPD_SUM. The Y cirulating power went up by 2.5W and the X by 2W.

The fringe offset went up by 8.8e-4 counts in that time.
