INSTRUMENT      : os75

ACQUISITION     :
     PROGRAM    : uhdas
     PING TYPE  : nb

     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)

                  yy/mm/dd  hh:mm:ss   BT   SI  NB  BL  TD BK     HO     HB CRPH

HEADING         :
     PRIMARY    : gyro
     CORRECTION : ashtech

POSITIONS       : gps (specify more detail if available)

CALIBRATION     : original heading alignment: 43.5
                  additional rotation -0.11
                  final transducer angle estimate is 43.5 - (-.11) = 43.61
                         (original transducer angle) - (rotate_angle)
                  original scale factor 1
                  additional (negligible) tweak of 1.0035 was applied

COMMENTS        : long ashtech gap 330.05-340.2;
                  no ashtech data at all, 345.05-345.3
                  very long ashtech gap 351.95-354.05
                  very long ashtech gap 364.45 - 368

                  Fortunately, the heading correction appears to be locked in
                  at about 0.8 +-0.1, so we're not in bad shape
