Modelling of shock-cooling light curve of SN 2017ckj using Light Curve Fitting package (Hosseinzadeh et al. 2024) based on the shock-cooling model of Sapir & Waxman (2017). The posterior probability distributions of the model parameters are shown, including the temperature 1 day after explosion (T₁), the total luminosity 1 day after explosion (L₁), the time at which the envelope becomes transparent (t_tr), and the time of explosion (t₀). The best-fit values of these parameters and their 1σ credible intervals are provided at the top.
