15a ped stability day 47, take 2

Under:
On August 8, BSMD peds in the offline DB where corrected for day 47.
Runs minb 34 & 74 were used to determine and upload DB peds.
Below I evaluated pedestal residua for 2 runs : 37 & 70, both belonging to the same RHIC fill.
I have used 500 zero-bias events from runs 37 & 70, for the official production w/o zero suppression.
All strips for which mTables->getStatus(iEP, id, statPed,"pedestal"); returns !=1 and all events using CAP123,124,125 were dropped.
Fig 1,2 show big picture: all 38,000 strips.
Fig 3 is zoom in on some small & big problems.
Fig 4 & 5 illustrates improvement if run-by-run pedestal is used.
Fig 1, run=9047037

Fig 2, run=9047070

Fig 3, run=9047070, zoom in

Private peds were determine for 16 runs for day 47 and used appropriately. Below is sum of ped residua from all 16 runs, from zero bias events.
