SHIP NAME       : Ronald H. Brown 
LAST CHANGED    : Fri Aug 20 11:29:48 HST 2004

CRUISE          : A16S (rb0501)
CRUISE DATES    : 2005/01/11 to 2005/02/26

CHIEF SCIENTIST : Rik Wanninkhof
DB_NAME         : a0501
DATA FILES      : pingdata.000 - pingdata.048
STATUS          : averaged, loaded, edited, heading corrected, done.

INSTRUMENTs     : NB150

ACQUISITION
     PROGRAM    : DAS2.48

     PING TYPE  : narrowband
      PARAMS    : blank=            8  (BK) (see adcpdb/\*cnh after first pass)
                  pulse =           8  (PL)
                  bin length=       8  (BL)
                  number of bins=   56  (NB)
HEADING
     PRIMARY    : gyro
     CORRECTION : aging Seatex

POSITIONS       : unknown GPS

CALIBRATION     : first application, 0.35deg, amplitude 1.009, then edit


COMMENTS        : Ron Brown Seapath often flakes out on turns, at station
                : boundries, and at will.  No QC info available (because of its
                : ancient firmware) but wild swings in cross-track velocity
                : are the big clue.  This often kills watertrack
                : calibrations.

                : The GPS used for positions if aft starboard; the transducers are
                : forward center.  A translation is used to try and compensate
                : for this, which has moderate success.  There are still a few small (few
                : cm/s) velocity transients at some on/off station boundaries.

(1) command line:

    cd A16S
    cd ping;
    ln -s /home/moli4/datasets/ron_brown/A16S/PINGDATA.* .
    cd ..

(2a) set up control file:

    q_py.cnt: (for first processing)

  ###   q_py.cnt is
   --yearbase 2005                            ### for decimal day conversion
   --dbname a0501                             ### database name, in adcpdb
   --use_refsm                                ### could use --use_smoothr
   --datatype pingdata                        ### this is the default
   --datafile_glob PINGDATA.???               ### DO NOT quote the wildcards
   --auto
   ### end of q_py.cnt

(2b) run it:
