//   MExtractPedestal
//
//  Pedestal Extractor base class
//
//  Input Containers:
//   MRawEvtData
//   MRawRunHeader
//   MRawEvtHeader
//   MGeomCam
//   MPedestalCam
//
//  Output Containers:
//   MPedestalCam
//
//  This class should be used for pedestal extractors with the following facilities:
//  a) Standardized calculation of AB-noise, mean pedestals and RMS
//  b) Standardized treatment of area- and sector averaged pedestals values
//  c) Possibility to use a signal extractor to be applied on the pedestals
//  d) Possibility to handle two MPedestalCams: one for the signal extractor and 
//     a second to be filled during the pedestal calculating process.  
//
//  ad a): Every calculated value is referred to one FADC slice (e.g. Mean pedestal per slice),
//         RMS per slice. 
//         MExtractPedestal applies the following formula (1):
// 
//         Pedestal per slice = sum(x_i) / n / slices
//         PedRMS per slice   = Sqrt(  ( sum(x_i^2) - sum(x_i)^2/n ) / n-1 / slices )
//         AB-Offset per slice = (sumAB0 - sumAB1) / n / slices 
//
//         where x_i is the sum of "slices" FADC slices and sum means the sum over all
//         events. "n" is the number of events, "slices" is the number of summed FADC samples.
// 
//         Note that the slice-to-slice fluctuations are not Gaussian, but Poissonian, thus 
//         asymmetric and they are correlated.
// 
//         It is important to know that the Pedestal per slice and PedRMS per slice depend 
//         on the number of used FADC slices, as seen in the following plots:
//
//Begin_Html
/*
<img src="images/PedestalStudyInner.gif">
*/
//End_Html
//
//Begin_Html
/*
<img src="images/PedestalStudyOuter.gif">
*/
//End_Html
//
//        The plots show the inner and outer pixels, respectivly and have the following meaning:
// 
//        1) The calculated mean pedestal per slice (from MPedCalcPedRun)
//        2) The fitted mean pedestal per slice     (from MHPedestalCam)
//        3) The calculated pedestal RMS per slice  (from MPedCalcPedRun)
//        4) The fitted sigma of the pedestal distribution per slice
//                                                  (from MHPedestalCam)
//        5) The relative difference between calculation and histogram fit
//           for the mean
//        6) The relative difference between calculation and histogram fit
//           for the sigma or RMS, respectively.
// 
//        The calculated means do not change significantly except for the case of 2 slices, 
//        however the RMS changes from 5.7 per slice in the case of 2 extracted slices 
//        to 8.3 per slice in the case of 26 extracted slices. This change is very significant.
// 
// ad b)  Every calculated value is referred to one FADC slice and one (averaged) pixel,
//        (e.g. Mean Pedestal per area index per slice per pixel, etc. )
//
//         MExtractPedestal applies the following formula (2):
// 
//         Averaged Pedestal per slice = sum(x_i) / n / slices / n_pix
//         PedRMS per slice   = Sqrt(  ( sum(x_i^2) - sum(x_i)^2/n ) / n-1 / slices / n_pix )
//         AB-Offset per slice = (sumAB0 - sumAB1) / n / slices / n_pix
//
//         where x_i is the sum of "slices" FADC slices and sum means the sum over all
//         events and all concerned pixels. 
//         "n" is the number of events, "slices" is the number of summed FADC samples and
//         "n_pix" is the number of pixels belonging to the specific area index or camera sector. 
// 
//         Calculating these averaged event-by-event values is very important to trace coherent
//         fluctuations. An example is given in the following plots:
//
//Begin_Html
/*
<img src="images/PedestalOscillations.gif">
*/
//End_Html
//
//        The plots show the extracted pedestals of the inner pixels (obtained
//        with MHPedestalCam), averaged on an event-by-event basis from 
//        run 13428 with switched off camera LV. 
//        The meaning of the four plots is:
// 
//        1) The distribution of the averaged pedestals
//        2) The averaged pedestals vs. time. 
//           One can see clearly the oscillation pattern
//        3) The fourier transform of the averaged pedestals vs. time. 
//           One can see clearly a peak at a certain frequency
//        4) The projection of the fourier components with the non-exponential
//           (and therefore significant) outlier.
//
//    ad c) Many signal extractors, especially those using a sliding window
//          have biases and their resolutions for zero-signals do not agree 
//          with the pedestal RMS. For the F-Factor method in the calibration
//          and the image cleaning, however, both have to be known and measured. 
//          
//          For this reason, a signal extractor can be handed over to the 
//          pedestal extractor and applied on the pedestal events with the 
//          function SetExtractor(). 
//          The results will get stored in an MPedestalCam. 
//        
//          Note that only extractors deriving from MExtractTimeAndCharge
//          can be used.
//
//   ad d)  The signal extractors themselves need a pedestal to be subtracted 
//          from the FADC slices. 
//          If the user wishes that the pededestals do not get overwritten by 
//          the results from the signal extractor, a different named MPedestalCam
//          can be created with the function: SetNamePedestalOut(). 
//
