Ejecta Velocity Study

These data were collected by Dr. Eri Tatsumi of the Univ of Tokyo at Jaxa. Dr. Barnouin of JHUAPL measured the ejecta velocities. The following table has some of the impact conditions. The target was coarse grained, with, in some instances, a buried block at the impact center.
