Caption: Figure 16.
Left: velocity profiles for [O I] λ6300 at δt = 259 days (red) and 412 days (blue). Gaussian profile fits shown in black demonstrate the potentially asymmetric distribution of O within the inner ejecta. Right: comparison of the [O I] λ6300 and Mg I] λ4570 velocity profiles, both displaying double-peaked profiles suggestive of clumping and/or asymmetries with the inner ejecta.
