Comparison of our model bolometric lightcurves with those of existing models. The solid lines show our model results, while the dashed and dotted lines correspond to the models of A. L. Piro et al. (2021) and B. Margalit (2022), respectively. The green lines represent the case with r_out = 10¹⁴ cm, χ = 1/7, M_CSM = 10⁻¹ M_⊙, and v_sh = 0.033c, while the orange and blue lines correspond to r_out = 3.2 × 10¹⁴ and 10¹³ cm, respectively, with all other parameters unchanged. For consistency, we note that we adopt an opacity of κ = 0.34 cm² g⁻¹ in this comparison.
