    115115    fit and the digital filter (eq.~\ref{eq:of_noise}).

    363363Figures~\ref{fig:sw:distped} through~\ref{fig:df:distped} show the
    364364extracted pedestal distributions for some selected extractors (\#18, \#23, \#25 and \#28)

    414414slice contents (``fundamental'') is displayed as red histogram, the one obtained from the application
    415 of time-randomized weigths on a fixed window of 2 FADC slices as blue histogram and the one obtained from the

    416416full algorithm allowed to slide within a global window of 12 slices. The obtained histogram means and
    417417RMSs have been converted to equiv. photo-electrons.}

     516We tested this relation assuming that the fitted area underneath the pedestal peak Area$_0$ is
    517517proportional to $P(0)$ and the sum of the fitted areas underneath the single photo-electron peak
    518 $Area_1$ and the double photo-electron peak $Area_2$ proportional to $P(>0)$. Thus, one expects:

    521 Area_0 / (Area_1 + Area+2 ) = \frac{e^{-R\cdot WS}}{1-e^{-R\cdot WS}}
