[Jenne, Sheila, Nutsinee, TJ]

We struggled for much of the afternoon trying to get the DRMI ASC to behave.  In the end, it seems that the SR3 OSEM values have changed now that we have a new satellite amplifier installed (see alog 25516 by Fil).  Sheila pointed out that we should trend both the WIT channels and the oplev channels for SR3, and then trust the oplev since nothing about it was changed today. 

In the attached plot, you can see that since we didn't move SR3 in yaw, the oplev value is constant but the WIT value is different.  Since the cage servo forces the WIT_P value to go to a constant pre-set value, it is the oplev that appears to move in pitch.  I have reset the SR3 cage servo setpoint to be 927, which is where it needs to be if we move SR3 so that we're back to the old oplev value.  This seems to have fixed things, and we were able to move on.

The OSEM inputs changed by about 20 counts each.
