The table of the 108 PRIME-1 campaign impacts can be found in Colwell et al. (2008). No coefficients of restitution could be measured for the PRIME-1 impacts. R rebound with no ejecta, E ejecta production, A asteroid-level parabola (0.05g), X no data available (regolith pillar), N/A no rebound from the projectile on the target could be observed
