Cruising close to Samoa Islands, went South West and back to Samoa, Apia port.

(1) review the data


    (a) check calibration:heading correction device:

             figview.py cal/rotate/*png

              conclude: no action needed

        figview.py .

    (b) check calibration:

   **watertrack**

Number of edited points:   5 out of  15
   amp   = 1.0014  + -0.0001 (t - 341.6)

phase      -0.0980  -0.2018   0.6773
------------

   **transducer-gps offset**  
------------
guessing ADCP (dx=starboard, dy=fwd) meters from GPS
positions from a_fk.agt

xducer_dx = 0.061699
xducer_dy = 1.569362
signal = 348.201976
------------

   **bottomtrack**  
------------
tail: cannot open 'cal/botmtrk/btcaluv.out' for reading: No such file or directory
------------

   (c) look at the data:

              dataviewer.py

(2)  edit "gautoedit"

    cd edit
    gautoedit.py -n5

    # apply editing:

      cd ..
      quick_adcp.py --steps2rerun apply_edit:navsteps:calib  --auto


    # check editing -- looks OK

          dataviewer.py

   amp   = 1.0014  + -0.0001 (t - 341.6)
   phase =  -0.23  + -0.0120 (t - 341.6)

signal = 348.201976
------------

# signal low 348 = no action needed.

(3) make web plots

       quick_web.py --interactive

 - view with a browser, look at webpy/index.html


(4) Extract data:

   quick_adcp.py --steps2rerun matfiles --auto

 You can extract NetCDF files as well.

   adcp_nc.py         adcpdb  contour/os75bb_short FK171110  os75bb
   adcp_nc.py  --long adcpdb  contour/os75bb_long  FK171110  os75bb

 To check netcdf file:

   ncdump -h contour/os75nb_short.nc
