With the run list of run08 pp data. I checked the pedestal run dependence for several ESMD stips.

  Fig1, U panel sector 2 strip 1.

    Fig 2, V panel sector 2 strip 1.

    Fig 3, U panel sector 4 strip 1.

    Fig 4, V panel sector 4 strip 1.

     The pedestals read from the histogram maximum bin center is stable for this strip, but the pedestal got from (raw ADC - pedestal subtracted ADC) is shifted by one ADC count in some runs. So I take 2 runs which see the pedestal shift and compare the distributions of the 2 runs.

    Fig5, the raw ADC distribution.

   Fig 6, the pedestal got from the ( raw ADC - pedestal subtracted ADC).
