For AttitudeSystem = 0, MJ2000 Zdirected unit vector component of the maneuver.
For AttitudeSystem = 1, Orbit BiNormal directed unit vector component of the maneuver.
For AttitudeSystem = 2, Nadir directed unit vector component of the maneuver.
For AttitudeSystem = 3, the Spacecraft's attitude is adjusted so that Spacecraft.EulerAngle3 is temporarily set to the value specified by FiniteBurn.Z_Component for the duration of the maneuver. The Euler angle is evaluated in degrees and is referenced to the Spacecraft's attitude reference frame. The Euler Sequence used by the FiniteBurn object is defined by the Spacecraft object's Euler Sequence. Individual thruster orientations defined in the Thruster object(s) are used for directing deltav.
For AttitudeSystem = 4, Intersection Normal to the Earth's Surface directed unit vector component of the maneuver.
For AttitudeSystem = 5, Orbit Normal directed component of the maneuver.
