The PCAL Team have updated the calibration (via EPICs record settings) on all of the real data streams of the displacement estimates for PCAL -- see LHO aLOGs 52828, 52853 and 52837 to account for recently identified systematic error.

I've accepted these changes (including the decision to update the force coefficient with the O2 / O3 mass problems with the force to displacement transfer function that was made later) in to the SDF system; both the safe and OBSERVE.snap.
