     PARAMETERS : BT : bottom track mode (on or off)
                  SI : sampling interval or averaging period for ensemble (sec)
                  NB : number of bins
                  BL : bin length (m)
                  TD : transducer depth (m)

CALIBRATION     : original heading alignment: 45.08
                  additional rotation 0
                  final transducer angle is:
                       (original transducer angle) - (rotate_angle)
                  original scale factor 1
                  additional scale factor (none)

COMMENTS        : gaps in heading correction?
                  scattering layers?
                  bubbles?
                  underway bias?
