Summary of ejecta properties for model s15p2Pwr1e40 at 350 d after explosion. From top to bottom, we show the mass density (scaled by the volume filling factor f_vol), the electron density (also scaled by f_vol), the volume filling factor f_vol, and a set of composition profiles and the (normalized) shock power. All quantities are shown versus ejecta velocity. The model without shock power has initially the same ejecta structure below 6000 km s⁻¹.
