CODAS+UHDAS metadata
---------------------

Depending on what information is desired, and the
history of the processing directory, information about
the data acquisition and processing may be found
in a variety of places.


 * CODAS processing tree from unknown origin:

   A binary program ``lst_cfg`` lists time ranges and 
       - transducer angle
       - bin size
       - blanking interval
       - bottom track on/off

   If quick_adcp.py was used, the listing will exist in
   the ``adcpdb`` directory as DBNAME.cnh (where DBNAME is 
   the database prefix).


  * Newer CODAS processing (after 2009) will include a file
    ``cruise_info.txt``,  which contains the output from ``lst_cnf. 

  * CODAS processing directories contain log files with 
      - a history of phase and amplitude corrections applied
      - a history of calibration calculations
      - the time-dependent heading correction applied
      - averaged editing criteria applied
      - single-ping editing thresholds applied

  * older at-sea CODAS processing of UHDAS data will contain
    two matlab files with processing parameters (transducer 
    angle, ancillary devices chosen) and directories used.
 
  * newer at-sea  CODAS processing of UHDAS data will contain
    the same two matlab files, and the python configuration files
    used to generate them.

  * all UHDAS cruise distributions contain the ``log`` directory 
    which has dialogs with the intrument, errors and warnings, 
    time of stop/start
