Since I was unable to get the PMC transmitted power back to where it was at the start of the run, I re-calibrated the PSL/IO rotation stage.  I followed the Jenne's instructions in alog 30479 and updated the PSL rotation stage Calibrate MEDM screen.  The only changes were the input power went from 49 W to 50.07 W and the minimum power angle changed from -25.2 to -24.78.  I've attached a screenshot of the data fit plotted in Matlab and the new rotation stage calibration screen.  These values are monitored in SDF, so I accepted these changes in the safe.snap SDF file (the OBSERVE.snap file did not register the change, so I'm guessing these channels are unmonitored in OBSERVE?).  No change was seen in the low power state the rotation stage is currently in, so hopefully when we request 37W into the IFO we are closer to 37W than we have been; we'll see how close this actually is as the IFO recovery from today's maintenance plays out.
