Notes. Iron emission lines taken from the NIST database are reported. Irel C/2020 F3 represents the relative intensity of our spectra at the iron emission wavelength, and σ represents the standard deviation of the continuum around the wavelength corresponding to the expected Fe I emission. (Fe I/CN3879.66 Å) represents the ratio between Irel C/2020 F3 and the relative intensity of the CN emission line at 3879.66 Å.
