Spectroscopic evolution of SN 2023ixf from maximum brightness to the nebular phase, highlighting the major absorption and emission lines. Spectra from day +2 (max brightness) to day +205 are taken from Perley (2023) and calibrated using the SPRAT automated pipeline (Barnsley, Smith & Steele 2012). Nebular spectra from day +291 to +413 were reduced following the method in Section 2 and have been overlaid with a Savitzky–Golay filter to reduce noise for clarity.
