PSL Rotation Stage Calibration

Since it hasn't been done since before the vent, and the output of the PMC has continued to slowly drop, before locking today I calibrated the PSL rotation stage following the steps in alog79596.

The measurement file, new calibration fit, and screenshot of accepting SDFs are all attached.
