Notes. The parameters shown are (left to right) shock time; shock normal vector (computed using MX3), θBn; magnetic compression ratio, rB; gas-compression ratio, r; shock speed, vsh (computed from mass-flux conservation); upstream plasma beta, βup; and fast magnetosonic and Alfvénic Mach numbers (Mfms and MA, respectively).
