Comparison between the observation of SN 2018bcc on the 14th of May 2018, 27.4 d after the estimated time of maximum at MJD= 58225.5, with the model spectrum based on a CDS mass and composition based on model he4p0, placed at a radius of 3 × 10¹⁵ cm, moving at a velocity of 2000 km s⁻¹ and powered at a rate of 2 × 10⁴² erg s⁻¹. The observed spectrum has been corrected for reddening (E(B − V) = 0.0124 mag) and redshift (z = 0.0636) and the model is normalized to the observations at 5300 Å. Both are smoothed with a Gaussian kernel (FWHM of 23.5 Å). The data and characteristics of SN 2018bcc are taken from Karamehmetoglu et al. (2021).
