Decomposed PNS kick velocities for models L_2.25 (top panel), L_2.3 (middle panel) and L_2.4 (bottom panel), obtained by integrating equation (4) from bounce. We have inverted the velocities for the L_2.3 run. The dot–dashed black curve depicts the PNS velocity computed using the centroid of the density, while the solid red curve shows the contributions to the kick from momentum flux (long-dashed blue curve), gravity (dashed green curve) and pressure (dot–dashed pink curve). In each run, the PNS is still accelerating at more than 500 km s⁻² at the end of the calculation, and this acceleration is dominated by the gravitational term.
