Class Description

 Service class for 2-Dim histogram classes

  TH2C a 2-D histogram with one byte per cell (char)
  TH2S a 2-D histogram with two bytes per cell (short integer)
  TH2F a 2-D histogram with four bytes per cell (float)
  TH2D a 2-D histogram with eight bytes per cell (double)

*-*-*-*-*-*-*-*Return correlation factor between axis1 and axis2*-*-*-*-*
*-*            ====================================================

*-*-*-*-*-*-*-*Return covariance between axis1 and axis2*-*-*-*-*
*-*            ====================================================

 fill the array stats from the contents of this histogram
 The array stats must be correctly dimensionned in the calling program.
 stats[0] = sumw
 stats[1] = sumw2
 stats[2] = sumwx
 stats[3] = sumwx2
 stats[4] = sumwy
 stats[5] = sumwy2

*-*-*-*-*-*-*-*Reset this histogram: contents, errors, etc*-*-*-*-*-*-*-*
