Summary:





    46
    
    
    
Within a short time (several days), pedestals are stable and do not show dependence on HVs.





    47
    
    
    
The largest change in pedestal happended to CerSum (ch8.03), which is 8.9 adc unit between HV off and HV on.





    48
    
    
    
The 2nd large change in pedestal happened to SC_D (ch8.00), which is 2.3 adc unit between HV off and HV on.
