[ROOT] Chi2 wrong on 2D fits

  Dear rooters,
  In the following small CINT macro lemaire1.C I make a 2d fit and calculate
after that the chi2 of the fit. The problem is that the chi2 I calculate is
not equal to the chi2 published by ROOT (which in fact is calculated by
Minuit). Have you any idea of what happens?
  The macro is simply launched by:

  .x lemaire1.C

  Thanks a lot for your help
