(1) Summary of the cruise:

    cd os75bb
    plot_nav.py nav/a_fk.gps

    Almost 20 days on station in the Gulf of California (~ 24N, 117W)


(2) review the data


    (a) check calibration:heading correction device:
    
    . Generating figures:
    
             quick_mplplots.py --yearbase 2018 --cruiseid FK181031
    
           (  figview.py cal/rotate/*png  )
	     
    - No gaps in the heading correction 
           
    (b) check calibration:

   **watertrack**   
------------
Number of edited points:   5 out of   5
   amp   = 0.9958  + -0.0014 (t - 310.0)
   phase =  -0.07  + -0.0389 (t - 310.0)
            median     mean      std
amplitude   0.9960   0.9958   0.0022
phase      -0.2350  -0.0672   0.3358
------------

>> Not enough points for calibration

(3)  edit: dataviewer.py -e

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


    check calibration:

   **watertrack**   
------------
Number of edited points:   5 out of   5
   amp   = 0.9962  + -0.0012 (t - 310.0)
   phase =   0.00  + -0.0990 (t - 310.0)
            median     mean      std

    # check editing

     dataviewer.py

    -- looks OK



(4) make web plots

       quick_web.py --interactive

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


(5) Extract data:

   quick_adcp.py --steps2rerun matfiles --auto


 You can extract NetCDF files as well.

   adcp_nc.py         adcpdb  contour/os75bb_short FK181031  os75bb
   adcp_nc.py  --long adcpdb  contour/os75bb_long  FK181031  os75bb

 To check netcdf file:

   ncdump -h contour/os75bb_short.nc
