Notes. Model estimates were computed using the algorithm described in Appendix A.2. We also include literature comparison values for iPTF13bvn in this table, from Lyman et al. (2016). For iPTF13bvn, hydrodynamical modelling also provided an ejecta mass of ≈2 M_⊙ (Fremling et al. 2016; Bersten et al. 2014). The models are: A82-c (c for compact; Appendix A) for small R₀ and A82-e (e for extended; Appendix A.1) for large R₀.
