1) Right arm preshower: channel 11 (starting with 1) was noisy.
The problem is with the ADC+filter. I moved all first 16 channels
to the last group of this ADC: ROC2,ADC 22,ch.48-63 (the initial
position was ch.0-15).
2) Left arm Pion rejector prl2 ch.15 had a low signal.
I increased the HV from 1600 to 1800V (starting with cosmic run
1023).
