IAgSnPtGrazingAlt Interface for a sensor pointed in such a way that the boresight vector will graze the central body at a specified altitude.

AzimuthOffset	The azimuth offset, defining the plane in the parent object's body-fixed frame in which the sensor boresight lies. It is the angle between the X axis and the azimuth vector in the XY plane. Uses Angle Dimension.
GrazingAlt	The altitude at which the boresight vector grazes the central body. Uses Distance Dimension.
