                        (see   cal/rotate/ens_hcorr.ang)

POSITIONS       : gps positions from posmv_gps



CALIBRATION     : (check original processing parameters)
                  (1) transducer alignment
                      original transducer alignment: 0.21
                      additional rotation 0
                      final transducer angle = origin - (correction)
                      final transducer angle is: 0.21

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

                  (3) ADCP (dx=starboard, dy=fwd) meters from GPS
                      original:        xducer_dx=1          xducer_dy=-10
                      correction           0                 0
                      final offset         1                -10




COMMENTS        : No additional calibrations are needed.  Acquisition
                  parameters are consistent with recent cruises.
                  Data below the bottom was removed, as well as small
                  bits of data at the bottom of the sonar's range.

==================================================
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

# I ran this looking for missing heading correction values:
dataviewer.py

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

No calibration adjustments, and no calibration values

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

# I ran this go through the dataset and edit out bad values:
dataviewer.py -e

# I ran this to recompute the calibration residuals:
quick_adcp.py --steps2rerun navsteps:calib --auto

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

# Has this corrected the problems in the original?
dataviewer.py -c . ../os38nb.orig


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

# To carry over the section info from another sonar.
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/os38nb  FKt231218 os38nb --ship_name "Falkor (too)"

# I ran this to look at the headers:
ncdump -h contour/os38nb.nc | egrep '(cruise_id|sonar|yearbase|platform)'
