HERACLES light curves for different ejecta-CSM configurations. We compare the bolometric light curves obtained with HERACLES for ejecta-CSM configurations corresponding to case-(1) and case-(2), as described in Section 2.1. We limit the sample for wind mass-loss rates covering from 10⁻⁵ to 0.1 M_⊙ yr⁻¹ with an additional density scaling of 1/R. The light curve degeneracy discussed in Sect. 3 is present throughout the sampled mass-loss rate range. Filled dots correspond to the inferred values for SN 2020tlf (Jacobson-Galán et al. 2022).
