LOGGING         : 

     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)
                  BK : blanking length (m)
                  HO : heading offset applied by DAS (deg)
                  HB : heading bias (deg)
                  CRPH : compensation for roll-pitch-heading, 1:on, 0:off)

HEADING         : 
     PRIMARY    : gyro
     CORRECTION : phins

POSITIONS       : gps (specify more detail if available)

CALIBRATION     : original heading alignment: 66.9
                  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?
