Errors quoted are the uncertainties measured when fitting Gaussian profiles to the emission lines of the host galaxies. For the host of SN~2007bi an additional component is included in the errors to account for the uncertainty of subtracting off the SN~continuum (set~at a conservative~20\% of the measured line flux).} \end{table}
