Multicomponent Gaussian fit to the [O I] λλ 6300,6364 and Hα emission complex in the 445 d spectrum of SN 2023ixf (red line). The sum of all six Gaussian components that fits the observations is shown with a blue line. Two components are associated with the [O I] λλ 6300,6364 feature (gray lines), while the other four components reproduce the Hα profile (green lines). See the text for further explanations.
