HEADING         : 
     PRIMARY    : heading from gyro
     CORRECTION : heading correction from posmv
                        NOTE: time-dependent heading corrections
                        applied IN the ensembles
                        (see   cal/rotate/ens_hcorr.ang)

POSITIONS       : gps positions from cnav

CALIBRATION     : (check original processing parameters)
                  additional rotation 0
                  final transducer angle is:
                       (original transducer angle) - (rotate_angle)
                  applied scale factor 1
                  additional scale factor (none)

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