    keyword=HRSR preshower - a wide pedestal

    The channel 11 (if the numbering starts with 1) of the preshower (ADC 22, #10) has a wide pedestal, if any preshower channel is connected to this ADC channel, via a 60Hz filter or directly. If the ADC channel is disconnected from a PMT - the pedestal becomes narrow. For the moment, the preshower channels 11 and 1 are swapped and the wide pedestal affects the top module in the right column (1).
    The database has been modified swapping #1 and #11.
