Emission lines used to measure abundances of the host galaxies of SNe 2007bg and 2007bi.
Emission line	SN 2007bg	SN 2007bi
[O II] $\lambda3727$	-	3.75 $\pm$ 0.93
H $\beta$ $\lambda4861$	6.19 $\pm$ 0.69	1.20 $\pm$ 0.45
[O III] $\lambda4959$	8.45 $\pm$ 0.71	1.75 $\pm$ 0.95
[O III] $\lambda5007$	17.81 $\pm$ 1.82	3.53 $\pm$ 1.07
H $\alpha$ $\lambda6563$	16.01 $\pm$ 1.62	3.33 $\pm$ 0.84
[N II] $\lambda6584$	0.91 $\pm$ 0.13	<0.43

Notes. Emission line fluxes in units 10^-17 erg s^-1 cm². 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).
