CRUISE          : P2_leg2 (mv0408)
CRUISE DATES    : 2004/07/28 to  2004/08/27
PORTS           : Honolulu to San Diego
CHIEF SCIENTIST : Jim Swift
DB_NAME         : a0408
DATA FILES      : VANC33MV*_000000.LTA (034-046, 048)
STATUS          : done processing LTA data; heading is corrected,
                        edited, calibration applied
INSTRUMENT      : OS75

ACQUISITION
     PROGRAM    : VmDAS

     see adcpdb/a0408.cnh
     PING TYPE  : narrowband                         broadband+bottomtrack
      PARAMS    : blank=          8                  8
                  pulse =         16                 8
                  bin length=     16                 8
                  number of bins= 50, 60, or 65      80
HEADING
     PRIMARY    : gyro
     CORRECTION : Ashtech (headings from nb150 ue4)

POSITIONS       : gps receiver

CALIBRATION     : final angle of transducers relative to ashtech:
                   transducer orientation + 2.56 + (-1.05) = 45 + 1.51

COMMENTS        : some top-bin underway ringing days 225-228
                  acoustic interference (??) 234

                : probably no need to redo processing with single-ping data
                  since 16m NB data looks good
