 NAME:     LArAutoCorrMaker.h
 PACKAGE:  offline/LArCalorimeter/LArCalibUtils
 
 AUTHORS:  M. AHARROUCHE
 CREATED:  Dec. 16, 2003
  
 PURPOSE:  Selects the good events and computes the autocorrelation 
           matrix for each cell. It processes all the gains
           simultaneously.
           In fact only the last (m_nsamples-1) elements of the 
           first line (or column) of autocorrelation matrix are
           computed and stored in TDS, for these reasons:
           - symetrie of autocorrelation matrix
           - equivalence of autocorrelation elements: 
             B(n,n+i)\eq B(m,m+i) (eg B12 \eq B23).
