# Table 1 Pre-impact parameters. Each collision in the dataset is uniquely defined by a set of 12 parameters. These parameters define the geometry of the collision and the physical characteristics, rotations, and orientations of the bodies involved in the collision. The subscripts ∞, targ, and proj refer to the asymptotic, target, and projectile values, respectively. The unit $$R_{\mathrm{grav}}$$ corresponds to maximum asymtotic impact parameter that will result in a collision
