CALIBRATION     : original heading alignment: 66.9
                : need it to be 67.30 , so -0.4 calibration
                :     (consistent with watertrack)
                :  :     tweak by -0.5
                : amplitude:  1.00 amplitude, tweaked by 1.006


COMMENTS        : ho heading correction: phins was coming in the gyro port.

      adcptree.py  os75nb --datatype uhdas --cruisename at15_62


(3) change directories to ADCP processing directory just created

    cd  os75nb


(4) create a quick_adcp.py control file

    unix: this example  is written as a bash "heredoc" for
          cut-and-past ease, but you can create q_py.cnt with
          an editor to have the parts between (or including)
          the comments

cat << EOF > q_py.cnt

    ####----- begin q_py.cnt------------
    ## all lines after the first "#" sign are ignored
      --yearbase    2010
      --cruisename  at15_62   # used to identify configuration files
                              #  *must* match prefix of files in config dir

      --update_gbin   ## NOTE: You must remake gbins for python processing if
                      ## - you are not sure
                      ## - if parameters for averaging changed
                      ## - various other reasons.
                      ## ==> just do it, and put them somewhere else
                      ##     (see next argument)
      --py_gbindirbase gbin # (will put them locally)


      --configtype matlab  ## python processing can read either type

      --sonar       os75nb
      --dbname      aship
      --datatype    uhdas
      --ens_len     300

      --ping_headcorr        ## applies heading correction.
                             ##     settings found in config files
      --proc_engine python   ## use python to do calculations
      --configtype python

      --max_search_depth 500    ## do not look for the bottom in open ocean

----------
(5) run quick_adcp.py:

        quick_adcp.py --cntfile q_py.cnt --auto


----------
(6) (a) check calibration:heading correction device:

    figview.py cal/rotate/*png

    conclude: no action needed


 (b) check calibration:



   **watertrack**   
------------
Number of edited points:   5 out of   7
   amp   = 0.0132  + 1.0040 (t -  69.8)
   phase =   0.51  + -0.4402 (t -  69.8)
            median     mean      std
amplitude   1.0000   1.0040   0.0095
phase      -0.6250  -0.4402   0.5728
------------


    **watertrack**  (cal/watertrk/adcpcal.out)
-------------------
(7)  edit "gautoedit" (go to "edit" directory with command line,
    type "gautoedit.py"

    # apply editing:


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

    # check editing -- looks OK

          dataviewer.py


    - check calibrations again


EG. still need scale factor:


    quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_amplitude 1.006 --rotate_angle -0.5 --auto



   **watertrack**   
------------
Number of edited points:   5 out of   7
   amp   = 0.0128  + 0.9978 (t -  69.8)
   phase =   0.52  + 0.0564 (t -  69.8)
            median     mean      std
