ALIGNMENT CHARACTERISTICS plane–the angle, projected into reaction plane, between the direction defined by the relative velocity of the CM of the system PLF-IMF to TLF and the direction defined by the relative velocity of PLF to IMF. Alignment and large deviations from Viola systematics are closely related. Asystiff, b=6,7,8 fm
