Notes. The two left columns give the name of the 3D hydrodynamic explosion model and the helium-core mass of the corresponding pre-SN model. The next three columns provide the averaged characteristic velocities for the bulk of ⁵⁶Ni containing 96% of the total ⁵⁶Ni mass in the 3D simulations; is the weighted mean velocity of the bulk mass of ⁵⁶Ni with the ⁵⁶Ni mass fraction as weight function at day 150; is the maximum velocity of the bulk mass of ⁵⁶Ni at the same epoch; and is the maximum velocity of the bulk mass of ⁵⁶Ni at the moment just after the main shock has passed the (C+O)/He composition interface. The last three columns give the 1D hydrodynamic properties of the progenitors: (ξ/ξ₀)^CO is the maximum time-integrated Rayleigh–Taylor growth factor in the close vicinity of the (C+O)/He composition interface (Fig. 3); Δ t_RS is the formation time of the reverse shock below the He/H composition interface, which is reckoned from the moment when the main shock crosses this composition interface; and R_RS is the radius of the reverse shock at the formation epoch.
