 AliTPCCalPad destructor

 Assignment operator

 Copy function

 Set AliTPCCalROC copies values from 'roc'
 if sector == -1 the sector specified in 'roc' is used
 else sector specified in 'roc' is ignored and specified sector is filled

 replace constent with median in the neigborhood

 replace constent with LTM statistic  in  neigborhood

 replace constent with median in the neigborhood

 add constant c1 to all channels of all ROCs

 multiply each channel of all ROCs with c1

 multiply AliTPCCalPad 'pad' by c1 and add each channel to the coresponing channel in all ROCs
  - pad by pad -

 multiply each channel of all ROCs with the coresponding channel of 'pad'
     - pad by pad -

 divide each channel of all ROCs by the coresponding channel of 'pad'
     - pad by pad -

 Reset all cal Rocs

   type=1 - mean
        2 - median
        3 - LTM

 Calculates mean and RMS of all ROCs

 return mean of the mean of all ROCs

 return mean of the RMS of all ROCs

 return mean of the median of all ROCs

 return mean of the LTM and sigma of all ROCs

 make 1D histo
 type -1 = user defined range
       0 = nsigma cut nsigma=min

 Make 2D graph
 side  -  specify the side A = 0 C = 1
 type  -  used types of determination of boundaries in z

 Loops over all AliTPCCalROCs and performs a localFit in each ROC
 AliTPCCalPad with fit-data is returned
 rowRadius and padRadius specifies a window around a given pad in one sector.
 The data of this window are fitted with a parabolic function.
 This function is evaluated at the pad's position.
 At the edges the window is shifted, so that the specified pad is not anymore in the center of the window.
 rowRadius  -  radius - rows to be used for smoothing
 padradius  -  radius - pads to be used for smoothing
 ROCoutlier -  map of outliers - pads not to be used for local smoothing
 robust     -  robust method of fitting  - (much slower)
 chi2Threshold: Threshold for chi2 when EvalRobust is called
 robustFraction: Fraction of data that will be used in EvalRobust

 Loops over all AliTPCCalROCs and performs a globalFit in each ROC
 AliTPCCalPad with fit-data is returned
 chi2Threshold: Threshold for chi2 when EvalRobust is called
 robustFraction: Fraction of data that will be used in EvalRobust
 chi2Threshold: Threshold for chi2 when EvalRobust is called
 robustFraction: Fraction of data that will be used in EvalRobust
 err: error of the data points
 if fitParArr and/or fitCovArr is given, write fitParameters and/or covariance Matrices into the array

 create an array of TFormulas for the each parameter of the fit function

 evaluate the fit formulas

 Performs a fit on both sides.
 Valid information for the fitFormula are the variables
 - gx, gy, lx ,ly: meaning global x, global y, local x, local y value of the padName
 - sector:         the sector number.
  eg. a formula might look 'gy' or '(sector<36) ++ gy' or 'gx ++ gy' or 'gx ++ gy ++ lx ++ lx^2' and so on

 PadOutliers - pads with value !=0 are not used in fitting procedure
 chi2Threshold: Threshold for chi2 when EvalRobust is called
 robustFraction: Fraction of data that will be used in EvalRobust
