to the core of the explosion than oxygen. @Filippenko02 stated that the \] $\lambda$4571 feature was the strongest (relative to \[\] $\lambda\lambda$6300, 6364) ever seen in a SN. We investigate this claim more closely and the results are shown in Table \[t:lines\], where we list the relative line strengths for each nebular spectrum of [SN 2001ig]{} along with some of the values from @Foley03 [Table 6] and values calculated from other SN spectra in the literature. To compute the relative line strengths for [SN 2001ig]{} we subtracted a local continuum from each spectral feature and then integrated the flux in each line. This is the same procedure presented by @Foley03.
