HEADING         :
     PRIMARY    : heading from gyro
     CORRECTION : heading correction from posmv
                        NOTE: time-dependent heading corrections
                        applied IN the ensembles
                        (see   cal/rotate/ens_hcorr.ang)

POSITIONS       : gps positions from gpsnav

CALIBRATION     : original transducer angle 51.7
                  additional rotation -0.2
                  final transducer angle is:
                       (original transducer angle) - (rotate_angle)
                          51.7 - (-0.2) = 51.9
                  applied scale factor 1
                  additional scale factor (none)

COMMENTS        : - wire interference common

Cruise RB-23-01_GO-SHIP_Leg2 processing:

The os75nb at-sea processing directory was copied from
the "proc" directory of the RB-23-01_GO-SHIP_Leg2 cruise disk.

All postprocessing is done with full codas+python (i.e. using
numpy+matplotlib)

(1) evaluate


(2) linked Leg2 with Leg2_A using link_uhdaslegs.py


(3) ran adcp_database_maker.py to make
        os75nb
        os75bb

    using the following dxdy correction
        xducer_dx   -5
        xducer_dy   6


(4) check accurate heading device (POSMV):
- look at figures in cal/rotate *hcorr.png for gaps
  (gaps would be red "+" signs -- there are none)


	 figview.py cal/rotate/*png

conclude: corrections required at the following ddays - [102.9, 106.3]


(4.5) ran patch_hcorr.py to fill missing heading data points


(5) check calibration:


      (a)  look at heading correction: are there gaps? does it need to be patched?
      (b)  look at watertrack and bottom track calibrations: what can we expect?


(a) catwt.py


 ADCP watertrack calibration
Number of edited points: 151 out of 152
   amp   = 1.0025  + 0.0002 (t - 118.1)
   phase =  -0.01  + -0.0039 (t - 118.1)
            median     mean      std
amplitude   1.0020   1.0024   0.0059  <--- no scale factor
phase      -0.2150  -0.2081   0.4553  <--- phase adjustment needed (-0.2)


  ===> look at the watertrack figures:

  figview.py cal/watertrk/*png


 (b) cal/botmtrk/btcaluv.out  (no bottom track)


conclude: no action needed


(6) Edit out any bad points or profiles, or the data below the bottom using

    dataviewer.py -e


(7) Recalculate the calibrations

    quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_angle -0.2 --auto

    catwt.py

Number of edited points: 147 out of 152
   amp   = 1.0023  + 0.0002 (t - 118.0)
   phase =  -0.02  + -0.0043 (t - 118.0)
            median     mean      std
amplitude   1.0020   1.0023   0.0059  <--- within 0.3% of one
phase      -0.0230  -0.0163   0.4494  <--- within 0.05deg of zero


(8) use of 'uvship' algorithm cleans up a dozen profiles or so.  Apply it here

    quick_adcp.py --steps2rerun navsteps:calib --refuv_source uvship --auto

(9) Make plots and files


Make web plots

    quick_web.py --interactive




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

### Run this to extract a netCDF file
adcp_nc.py adcpdb contour/os75nb  RB2301_leg2 os75nb --ship_name RON_BROWN

### Run this to look at the headers
ncdump -h contour/os75nb.nc
