    282 \item[Time Extraction Type:\xspace] The position of the maximum can be chosen (default) or the
    283 position of the half maximum at the rising edge of the pulse

     283position of the half maximum at the rising edge of the pulse (default).
    284284\item[Charge Extraction Type:\xspace] The amplitude of the maximum can be chosen (default) or the
    285285integrated spline between maximum position minus rise time (default: 1.5 slices) and maximum position plus
    286 fall time (default: 4.5 slices). The low-gain signal integrates one slice more at the falling part of the
