au is an estimated initial shock velocity based on the average velocity of the shock in the crystal, the assumption that the
shock advanced at a constant velocity, and allowance for experimental complications.
boot is the average level at which detonation overtook the shock front in the crystal.
Ct,T is the average time at which detonation overtook the shock front in the crystal.

eOvertake occurred after the initial shock had crossed the 7.4-mm-thick crystal. tOT includes the time needed to overtake
the crystal’s moving free surface.
