	Name	Description
	VectorBPlane	Initializes a new instance. By default the CentralBody will be Earth and the GravitationalParameter will be set to GravitationalParameter.
	VectorBPlane(VectorBPlane, CopyContext)	Initializes a new instance as a copy of an existing instance.
	VectorBPlane(Point, CentralBody, Double)	Initializes a new instance.
	VectorBPlane(Point, CentralBody, Double, ReferenceFrame)	Initializes a new instance.

	Name	Description
	CentralBody	Gets or sets the CentralBody to use.
	GravitationalParameter	Gets or sets the gravitational parameter of the CentralBody.
	IsFrozen	Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so. (Inherited from DefinitionalObject.)
	OrbitalPoint	Gets or sets the Point to use when computing this VectorBPlane. This must provide position and velocity information.
	ParentReferenceFrame	Gets or sets the ReferenceFrame that the CentralBody will be defined in. If this is then the Z component of the CentralBodies fixed frame will be used in orientating the VectorBPlane.

	Name	Description
	Add	Add a vector to this one. (Inherited from Vector.)
	CheckForSameDefinition(DefinitionalObject)	Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object). (Inherited from Vector.)
	CheckForSameDefinition(Vector)	Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object). (Overrides VectorCheckForSameDefinition(Vector).)
	CheckForSameDefinition(VectorBPlane)	Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
	Clone	Clones this object using the specified context. (Overrides DefinitionalObjectClone(CopyContext).)
	ComputeCurrentDefinitionHashCode	Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the CheckForSameDefinition(DefinitionalObject) method. (Overrides VectorComputeCurrentDefinitionHashCode.)
	CreateVectorDerivative	Constructs a vector which represents a derivative of this vector. (Inherited from Vector.)
	Cross	Produce the vector cross product between this vector and another one. (Inherited from Vector.)
	Divide(Double)	Divide this vector by a scale factor. (Inherited from Vector.)
	Divide(Scalar)	Divide this vector by a scale factor. (Inherited from Vector.)
	Dot	Produce the vector dot product between this vector and another one. (Inherited from Vector.)
	EnumerateDependencies	Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class. (Overrides DefinitionalObjectEnumerateDependencies(DependencyEnumerator).)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	Freeze	Freezes this object. Further attempts to modify it will result in an ObjectFrozenException. (Inherited from DefinitionalObject.)
	FreezeAggregatedObjects	Called by Freeze to also freeze any objects that are considered to be a part of this object. Derived classes which contain additional aggregated objects MUST override this method, call the base implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be frozen in this method are frequently created in this object's constructor and are not settable via properties. (Inherited from DefinitionalObject.)
	GetBDotR	Returns a Scalar that represents the value of this VectorBPlane doted with the B-Plane R vector.
	GetBDotT	Returns a Scalar that represents the value of this VectorBPlane doted with the B-Plane T vector.
	GetDefinitionHashCode	Gets a hash code representing the definition of this object. (Inherited from DefinitionalObject.)
	GetEvaluator	Gets an evaluator that can be used to find the Motion<Cartesian> of this vector at a given date with respect to the axes in which it is defined. See GetEvaluator(EvaluatorGroup) for details. (Inherited from Vector.)
	GetEvaluator(EvaluatorGroup)	Gets an evaluator that can be used to find the Motion<Cartesian> of this vector in its parent Axes at a given JulianDate. Consider using the methods of GeometryTransformer instead of calling this method directly. (Overrides VectorGetEvaluator(EvaluatorGroup).)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetScalarElement(CartesianElement, Axes)	Gets a Scalar representing the X, Y, Z, or Magnitude of this vector. (Inherited from Vector.)
	GetScalarElement(CartesianElement, Axes, Int32)	Gets a Scalar representing the X, Y, Z, or Magnitude of this vector, or any derivative of those elements. (Inherited from Vector.)
	GetService	Gets the service object of the specified type. (Inherited from Vector.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsSameDefinition	Determines if this object has the same definition as another object. (Inherited from DefinitionalObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Multiply(Double)	Multiply this vector by a scale factor. (Inherited from Vector.)
	Multiply(Scalar)	Multiply this vector by a scale factor. (Inherited from Vector.)
	Subtract	Subtract a vector from this one. (Inherited from Vector.)
	ThrowIfFrozen	Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object. (Inherited from DefinitionalObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

The b-plane is the basis for a coordinate system that can assist in targeting a trajectory during a gravitational assist. The b-plane itself is the plane that is perpendicular to the incoming asymptote of a hyperbolic trajectory and centered on the planet it is approaching. To form the rest of the coordinates, that plane is aligned generally with the planets pole vector, or to the Z component of an arbitrary ParentReferenceFrame centered on the planet. This vector points to where the incoming asymptote intersects with the b-plane.

In its native frame, there is no Z component to this Vector. The X component is can be computed with the GetBDotT. Likewise the Y component, R, can be computed with GetBDotR.

Remember that this is not where the actual trajectory intersects with the b-plane, just the asymptote of a hyperbolic trajectory.
