Notes. The values for the winds were chosen in accordance with Dwarkadas (2014) for Type IIP and Grassitelli et al. (2021) for Type IIn SNe. Columns 2–3 give the mass-loss rate (2) and wind velocity (3) (assumed constant for the free wind), and Cols. 4–6 give the initial radius of the SN ejecta at the start of the simulation (4), the total ejecta mass of the SN (5), and the parameter n determining the radial dependence of the ejecta (6). Colums 7–9 give the shell mass (7), shell thickness (8), and the position of the shell (9) (see text for details).
