Beam calibration

Per beam calibration used to calculate derived raw variables and apply TVG.

Beam	Displays the beam number of the beam.
Transducer	Displays the beam's transducer.
Minor-axis beam steering angle	The MS70 Alongship beam steering angle (degrees) for the beam.
Major-axis beam steering angle	The MS70 Athwartship beam steering angle (degrees) for the beam.
Calibration source	Displays the transducer used as the Calibration source.
