    2828\item No switching noise due to the low-gain switch has been simulated.
    2929\item The intrinsic transit time spread of the photo-multipliers has not been simulated.
    30 \item The pulses have been simulated in steps of 0.2\,ns before digitization. There is thus an artificial numerial time resolution

    3232\item The total dynamic range of the entire signal transmission chain was set to infinite, thus the detector has been simulated
