FSS RevCav TPD Since Adjustment

Attached are 2 trends of the FSS RefCav TPD.  The first is a 14 day trend showing the last decay up until the 1-1-2016 lockloss and the subsequent RefCav adjustment.  The second is a 3 day trend detailing what the RefCav TPD has done since we adjusted it on 1-1-2016.  Since the adjustment the TPD has fallen by ~0.2 V to 1.31 V, but has appeared to level out there over the last 24 hours.  As it stands now no adjustment is necessary; 1.31 V on the TPD indicates that there is plenty of light for the ALS system to function correctly (danger zone is ~0.9 V on the TPD).  I will continue to monitor as this could change (but hopefully won't).
