class AliDielectronSignalBase: public TNamed

Dielectron SignalBase



Base class for signal extraction from a histogram or an array of histograms
The histogram is assumed to be an inv. mass spectrum,
the array of histograms is assumed to be an array with inv. mass histograms
resulting from single and mixed events, as defined in AliDielectron.cxx

void Process(TObjArray *const )

  This function needs to be implemented by the signal extraction classes.
  Here all the work should be done.

  The signal extraction is done on the mass spectra.
  The TObjArray should contain the Inv. Mass spectra of the 10 possible combinations
     for single and mixed events defined in AliDielectron.cxx
