An objects(i.e., instrument, detector, or item) orientation, with respect to True North. Its value is the angle subtended by a line from the center point of the object to True North in the horizontal plane and the line formed by the object's front-to-back axis projected onto the horizontal plane. The angle range is from "-180.0" to "+180.0" degrees. A value of zero implies the front of the object's body is pointed to True North; positive values imply the front is pointed to the east of True North; negative values imply the front is pointed to the west of True North.
