NTT-EFOSC2 spectrum of SN 2020zbf at +43.7 days after maximum light. The spectrum is corrected for MW extinction and is smoothed using a Savitzky-Golay filter. The original spectrum is shown in lighter colors. The colors depict the various elements and the question marks indicate that their presence in the spectrum is unclear. The ions beneath the spectrum are shown at the rest-frame wavelength, whilst those above have been shifted to match the absorption component.
