Profiles of the number density (n, panel a), the flow speed (u, panel b), the thermal pressure (P, panel c), and the temperature (T, panel d) immediately after the supernova explosion. Vertical grey lines mark the boundary of the supernova ejecta (up to 0.023 parsec), the free stellar wind (region 1), the shocked LBV and WR wind (region 2), the shocked wind from the O and B phases (region 3), the shocked ISM (region 4), and the ambient ISM (region 5). R_WT is the radius of the wind termination shock, LBV shell denotes the dense shell created by interaction between LBV wind and WR wind, and CD represents the contact discontinuity between shocked wind and shocked ISM.
