Average amplitude and RMS over pads for runs in the range 898-914

Average amplitude and their RMS is calculated over all "good" pixels for each ASIC
in each event. The event by event variation of the average amplitude demonstrates the "common-noise"
background. The value of RMS shows a spread of amplitudes over ASIC.  One would expect the event by event variation of RMS should be small.

In run 898 ASIC 4 and 8 RMS is step-wise changing from ~40 to ~90 ADC units. In ASICs 7 and 14  RMS is rising with event number...
