\caption{List of SNe used in the Hubble diagram. $m_I^{\rm eff}$ is
  the peak magnitude corrected for dust extinction and for the
  width-luminosity relation, following Eq.~(\ref{Imax}).  The quoted
  uncertainties do not include the redshift contribution due to
  peculiar velocities in the host galaxies, assumed equal to 300~km~s$^{-1}$. Redshifts from Table~\ref{Ifit_results} are here transformed into the CMB~frame.}
