Helium core mass, explosion energy and mass and distribution of the 56Ni as derived from the optical-to-MIR pseudo-bolometric lightcurve before day 400 in this work, and from the UV-to-MIR pseudo-bolometric lightcurves before days 80 and 100 in B12 and E15, respectively.

Notes. The errors are given in parenthesis and include those arising from the distance, extinction, and photospheric velocities (assumed to be 15 per cent), but do not take the degeneracy of the solution into account. The mass of the 56Ni given in B12 has been adjusted with respect to the distance and extinction (E14).
