Method:
from _private_ production w/o zero BSMD suppression we look at pedestal residua for raw spectra for minb events.

The only QA was to require MPV of the spectrum is below 100, one run contains ~80K events.
Good spectra look like this:
TOP: MPV value from all strips. White means 0 (zero) counts. Crate 4 was not evaluated.
BOTTOM: status table: red=bad, white means MPV>100 events
TOP: MPV value from all strips. White means 0 (zero) counts
BOTTOM: status table: red=bad, white means MPV>100 events
