POSITIONS       : gps positions from posmv_gps

CALIBRATION     : (check original processing parameters)
                  (1) transducer alignment
                      original transducer alignment: -1.33
                      additional rotation 0
                      final transducer angle is: -1.33

                  (2) scale factor
                      original scale factor 1
                      additional scale factor (none)

                  (3) ADCP (dx=starboard, dy=fwd) meters from GPS
                    original:            0                 0
                    correction           0                -14
                    final offset         0                -14

COMMENTS        : I performed a dxdy calibration. A good estimate of
                  heading correction and transducer offset is available from
                  adjacent cruises. Data below the bottom was removed,
                  as well as small bits of data at the the bottom of the
                  sonars range was removed. Due to a strong scattering
                  layer, some data was flagged as "below that bottom".
                  Some of this data was able to be reclaimed. Editing
                  and updating the dxdy correction improved the
                  data during heading changes.

==================================================
POST PROCESSING STEPS:
==================================================

------------------------------------------------------------------------------
### 1. Check visual oddities
------------------------------------------------------------------------------

# I ran this to look for gaps in the cruise track.
plot_nav.py nav/a*.gps

# I ran this to look for gaps in the heading correction.
figview.py

### Run this: (to interpolate for missing heading correction fixes)
cd cal/rotate
patch_hcorr.py
cd ../..

# I ran this to look for missing heading correction values or missing positions.
dataviewer.py

------------------------------------------------------------------------------
### 2. ADCP calibration
------------------------------------------------------------------------------

# Insufficient calibration information;
# use adjacent cruises for calibration values.


# I ran this to adjust the calibrations.
quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --xducer_dy -14 --auto

------------------------------------------------------------------------------
### 3. Editing points
------------------------------------------------------------------------------

# To go through the dataset and edit out bad values.
dataviewer.py -e

------------------------------------------------------------------------------
### 4. Check edited, calibrated dataset against original dataset
------------------------------------------------------------------------------

# Has this corrected the problems in the original?
dataviewer.py -c . ../wh300

# To compare this sonar with another sonar.
dataviewer.py -c ../os38nb  .

# The compartison is as expected. The wh300 has much higher resolution in the
# surface ocean.

------------------------------------------------------------------------------
### 5. Make plots and files
------------------------------------------------------------------------------

quick_web.py --interactive

# I ran this to extract matlab files.
quick_adcp.py --steps2rerun matfiles --auto

# I ran this to extract a netCDF file.
adcp_nc.py adcpdb contour/wh300 FKt230508 wh300 --ship_name "Falkor (too)"

# I ran this to look at the headers.
ncdump -h contour/wh300.nc | egrep '(cruise_id|sonar|yearbase)'

# Complete.
