This may be a rehash but WP review reminded me.  Re WP 5618

The attached 30 day trends of the three Ground STS2's Mass position shows that they are all out of spec.  The values for these should be something smaller than 5000 counts or 1.5 or 2 volts.  If it can be managed during Tuesday Maintenance without interfering with calibration or other work, I'd like to again try recentering these.  Much easier now given the remote capability.
