The unit vector in the Spacecraft body coordinate system that defines the primary axis (or z-axis) of the tank. The tank's fill line is oriented perpendicular to this axis. The tank's center of gravity is determined based on this fill line orientation, the tank reference location, tank volume, fuel mass, and fuel density.
