    3 \ldots {\it In this section, the extractors are described, especially w.r.t. which free parameters are left to play,
    4 how they subtract the pedestal, how they compare between calibration and cosmics pulses and how an
    5 extraction in case of a pure pedestal event takes place. }

     9\subsection{Implementation of Signal Extractors in MARS}
     10
     11All signal extractor classes are stored in the MARS-directory {\textit{\bf msignal/}}.
     12There, the base classes {\textit{\bf MExtractor}}, {\textit{\bf MExtractTime}}, {\textit{\bf MExtractTimeAndCharge}} and
     13all individual extractors can be found. Figure~\ref{fig:extractorclasses} gives a sketch of the
     14inheritances of each class and what each class calculates.

     20\end{figure}
     21
     22The following base classes for the extractor tasks are used:
     23\begin{description}
     24\item[MExtractor:\xspace] This class provides the basic data members equal for all extractors which are:
     25  \begin{enumerate}
     26  \item Global extraction ranges, parameterized by the variables
     27    {\textit{\bf fHiGainFirst, fHiGainLast, fLoGainFirst, fLoGainLast}} and the function {\textit{\bf SetRange()}}.
     28    The ranges always {\textit{\bf include}} the edge slices.
     29  \item An internal variable {\textit{\bf fHiLoLast}} regulating the overlap of the desired high-gain
     30    extraction range into the low-gain array.a
     31  \item The maximum possible FADC value, before the slice is declared as saturated, parameterized
     32    by the variable {\textit{\bf fSaturationLimit}} (default:\,254).
     33  \item The typical delay between high-gain and low-gain slices, expressed in FADC slices and parameterized
     34    by the variable {\textit{\bf fOffsetLoGain}} (default:\,1.51)
     35  \item Pointers to the used storage containers {\textit{\bf MRawEvtData, MRawRunHeader, MPedestalCam}}
     36    and~{\textit{\bf MExtractedSignalCam}}, parameterized by the variables
     37    {\textit{\bf fRawEvt, fRunHeader, fPedestals}} and~{\textit{\bf fSignals}}.
     38  \item Names of the used storage containers to be searched for in the parameter list, parameterized
     39    by the variables {\textit{\bf fNamePedestalCam}} and~{\textit{\bf fNameSignalCam}} (default: ``MPedestalCam''
     40    and~''MExtractedSignalCam'').
     41  \item The equivalent number of FADC samples, used for the calculation of the pedestal RMS and then the
     42    number of photo-electrons with the F-Factor method (see eq.~\ref{eq:rmssubtraction} and
     43    section~\ref{sec:photo-electrons}). This number is parameterized by the variables
     44    {\textit{\bf fNumHiGainSamples}} and~{\textit{\bf fNumLoGainSamples}}.
     45  \end{enumerate}
     46
     47  {\textit {\bf MExtractor}} is able to loop over all events, if the {\textit{\bf Process()}}-function is not overwritten.
     48  It uses the following (virtual) functions, to be overwritten by the derived extractor class:
     49
     50  \begin{enumerate}
     51  \item void {\textit {\bf FindSignalHiGain}}(Byte\_t* firstused, Byte\_t* lowgain, Float\_t\& sum, Byte\_t\& sat) const
     52  \item void {\textit {\bf FindSignalLoGain}}(Byte\_t* firstused, Float\_t\& sum, Byte\_t\& sat) const
     53  \end{enumerate}
     54
     55  where the pointers ``firstused'' point to the first used FADC slice declared by the extraction ranges,
     56  the pointer ``lowgain'' point to the beginning of the low-gain FADC slices array (to be used for
     57  pulses reaching into the low-gain array) and the variables ``sum'' and ``sat'' get filled with the
     58  extracted signal and the number of saturating FADC slices, respectively.
     59  \par
     60  The pedestals get subtracted automatically {\textit {\bf after}} execution of these two functions.
     61
     62\item[MExtractTime:\xspace] This class provides - additionally to those already declared in {\textit{\bf MExtractor}},
     63  the basic data members equal for all time extractors which are:
     64  \begin{enumerate}
     65  \item Pointers to the used storage containers {\textit{\bf MArrivalTimeCam}}
     66    parameterized by the variables
     67    {\textit{\bf fArrTime}}.
     68  \item The name of the used ``MArrivalTimeCam''-container to be searched for in the parameter list,
     69    parameterized by the variables {\textit{\bf fNameTimeCam}} (default: ``MArrivalTimeCam'' ).
     70  \end{enumerate}
     71
     72  {\textit {\bf MExtractTime}} is able to loop over all events, if the {\textit{\bf Process()}}-function is not
     73  overwritten.
     74  It uses the following (virtual) functions, to be overwritten by the derived extractor class:
     75
     76  \begin{enumerate}
     77  \item void {\textit {\bf FindTimeHiGain}}(Byte\_t* firstused, Float\_t\& time, Float\_t\& dtime, Byte\_t\& sat, const MPedestlPix \&ped) const
     78  \item void {\textit {\bf FindTimeLoGain}}(Byte\_t* firstused, Float\_t\& time, Float\_t\& dtime, Byte\_t\& sat, const MPedestalPix \&ped) const
     79  \end{enumerate}
     80
     81  where the pointers ``firstused'' point to the first used FADC slice declared by the extraction ranges,
     82  and the variables ``time'', ``dtime'' and ``sat'' get filled with the
     83  extracted arrival time, its error and the number of saturating FADC slices, respectively.
     84  \par
     85  The pedestals can be used for the arrival time extraction via the reference ``ped''.
     86
     87\item[MExtractTimeAndCharge:\xspace] This class provides - additionally to those already declared in
     88  {\textit{\bf MExtractor}} and {\textit{\bf MExtractTime}},
     89  the basic data members equal for all time and charge extractors which are:
     90  \begin{enumerate}
     91  \item The actual extraction window sizes, parameterized by the variables
     92    {\textit{\bf fWindowSizeHiGain}} and {\textit{\bf fWindowSizeLoGain}}.
     93  \item The shift of the low-gain extraction range start w.r.t. to the found high-gain arrival
     94    time, parameterized by the variable {\textit{\bf fLoGainStartShift}} (default: -2.8)
     95  \end{enumerate}
     96
     97  {\textit {\bf MExtractTimeAndCharge}} is able to loop over all events, if the {\textit{\bf Process()}}-function is not
     98  overwritten.
     99  It uses the following (virtual) functions, to be overwritten by the derived extractor class:
     100
     101  \begin{enumerate}
     102  \item void {\textit {\bf FindTimeAndChargeHiGain}}(Byte\_t* firstused, Byte\_t* logain, Float\_t\& sum, Float\_t\& dsum,
     103    Float\_t\& time, Float\_t\& dtime, Byte\_t\& sat,
     104    const MPedestlPix \&ped, const Bool\_t abflag) const
     105  \item void {\textit {\bf FindTimeAndChargeLoGain}}(Byte\_t* firstused, Float\_t\& sum, Float\_t\& dsum,
     106    Float\_t\& time, Float\_t\& dtime, Byte\_t\& sat,
     107    const MPedestalPix \&ped, const Bool\_t abflag) const
     108  \end{enumerate}
     109
     110  where the pointers ``firstused'' point to the first used FADC slice declared by the extraction ranges,
     111  the pointer ``lowgain'' point to the beginning of the low-gain FADC slices array (to be used for
     112  pulses reaching into the low-gain array),
     113  the variables ``sum'', ``dsum'' get filled with the
     114  extracted signal and its error. The variables ``time'', ``dtime'' and ``sat'' get filled with the
     115  extracted arrival time, its error and the number of saturating FADC slices, respectively.
     116  \par
     117  The pedestals can be used for the extraction via the reference ``ped'', also the AB-flag is given
     118  for AB-clock noise correction.
