+the bias $B$ has to be known beforehand.

+In the case of MAGIC the background fluctuations are due to electronics noise  and the PMT response to LONS. The signals from the latter background are not distinguishable from the Cherenkov signals. Thus each algorithm which searches for the signals inside the recorded FADC time slices will have a bias. In case of no Cherenkov signal it will reconstruct the largest noise pulse.

+Note that every sliding window extractor, the digital filter and the spline extractor has a bias, especially at low or vanishing signals $S$.
