The impact angle axis is scaled by probability such that the
horizontal extent of each regime is proportional to the likelihood
of that collision outcome. Mlr is the mass of the largest remnant
after the collision; Mtot is the sum of the projectile and target
mass; Vesc is the mutual escape velocity. Catastrophic disruption
is defined as the specific energy needed to gravitationally
disperse exactly half the total mass. Note that between perfect
merging and hit-and-run, there is a graze-and-merge regime. Some
perfect merging outcomes (e.g., for M

Partial wish list: Add reverse impact calculation for erosion of projectiles in hit-and-run events; add optional graze-and-merge regime; add optional probability scaling for velocity axis.
