  COMMENTS                    : 
This cruise has two instruments, 38kHz phased array ("Ocean Surveyor",
"OS38") capable of pinging in broadband or narrowband (or interleaved) modes,
and a 300kHz broadband "Workhorse" ADCP ("WH300"). Each instrument and pingtype
was processed separately, producing 3 ADCP datasets for this cruise.
These datasets OS38 broadband, OS38 narrowband, WH300, have
NODC SAC IDs 01540, 01541, and 01542, respectively.

Broadband data from an Ocean Surveyor gives greater resolution but less
depth penetration, Narrowband mode from the same instrument gives lower
resolution but deeper penetration.

The Workhorse 300 has the highest time- and depth- resolution, but
rarely reaches deeper than 80m.

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

(1) look at heading correction: are there gaps?

figview.py cal/rotate/*png

No gaps; it says everything is fine.

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

(2) check calibration -- what remains to be done?

	** watertrack **   (tail -20 cal/watertrk/adcpcal.out)

    Number of edited points:  26 out of  26
        amp   = -0.0013  + 1.0059 (t - 101.6)
        phase =   0.03  + 0.0110 (t - 101.6)
                    median     mean      std
        amplitude   1.0050   1.0059   0.0065
        phase      -0.1110   0.0110   0.5654

     (a) amplitude is within 0.5%  (.995 - 1.005) so "good enough" for the next step
     (b) phase (angle) is between (-0.2, 0.2) so  "good enough" for the next step

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

(3) edit: gautoedit.py ..

    from gautoedit, for every screen do
      - show now
	  - additional manual editing if necessary
	  - list to disk (creates/appends new a*.asc files with new flags)

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


(4) apply editing:

from dir os38bb:

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


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

(5) phase and amplitude calibration:

from dir os38bb:

quick_adcp.py --steps2rerun rotate:navsteps:calib:matfiles --rotate_amplitude 1.0055
              --rotate_angle -0.05 --auto

** applied corrections: **

           amp=1.0055
           phase=-0.05


** watertrack **   (tail -20 cal/watertrk/adcpcal.out)


    Number of edited points:  27 out of  27
        amp   = -0.0016  + 1.0002 (t - 101.7)
        phase =   0.02  + 0.0579 (t - 101.7)
