Notes. The mass values correspond to the amount of additional mass introduced to the ejecta by the density enhancement, under the assumption that the density enhancement is spherically symmetric. It is important to note that the material from the density enhancements is not required to be new material added to the system, and can be a redistribution of ejecta that would otherwise be located farther in at lower velocities.
