 Init what we need for the correction:

 Raw spectrum, hadron contamination
 MC efficiency maps, correlation matrix
 V0 efficiency if wanted

 This for a given dimension.
 If no inclusive spectrum, then take only efficiency map for beauty electron
 and the appropriate correlation matrix

 get spectrum for beauty 2nd method

 Correct the spectrum for efficiency and unfolding
 with both method and compare

 Correct the spectrum for efficiency and unfolding for beauty analysis
 with both method and compare

 Apply background subtraction

 calculate charm background

 calculate conversion background

 calculate non-HFE background

 Normalize the spectrum to 1/(2*Pi*p_{T})*dN/dp_{T} (GeV/c)^{-2}
 Give the final pt spectrum to be compared

 Normalize the spectrum to 1/(2*Pi*p_{T})*dN/dp_{T} (GeV/c)^{-2}
 Give the final pt spectrum to be compared

 Normalize the spectrum to 1/(2*Pi*p_{T})*dN/dp_{T} (GeV/c)^{-2}
 Give the final pt spectrum to be compared

 Normalize the spectrum to 1/(2*Pi*p_{T})*dN/dp_{T} (GeV/c)^{-2}
 Give the final pt spectrum to be compared

 Set the container for a given step to the

 Get Correction Framework Container for given type

 Slice bin for a given source of electron
 nDim is the number of dimension the corrections are done
 dimensions are the definition of the dimensions
 source is if we want to keep only one MC source (-1 means we don't cut on the MC source)
 positivenegative if we want to keep positive (1) or negative (0) or both (-1)
 centrality (-1 means we do not cut on centrality)

 Slice correlation

 Correct from the width of the bins --> dN/dp_{T} (GeV/c)^{-1}

 Correct statistical error

 Emulate garbage collection on class level

 Do a safe deletion

 Create efficiency grid and calculate efficiency
 of step to step0

 Return beauty electron IP cut efficiency

 Return PID x IP cut efficiency

 retrieve AliCFDataGrid for raw beauty spectra obtained from fit method
