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

(0) remake all the plots

quick_mplplots.py --plots2run all --yearbase 2022


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

    figview.py cal/rotate/*png

[X] There were no gaps! 
[] There WERE some gaps!

Did NOT run patch_hcorr.py.

(2) see what calibration looks like:

                amp  in [0.995, 1.005] : good enough to proceed 
                                         to the next step.  tweak later
                phase in (-.5, .5) : good enough to proceed 
                                         to the next step.  tweak later

    rule of thumb: errors when underway:

         scale factor of 1.02 (i.e. 2%) gives 10cm/s alongtrack error
         phase error of 1deg gives 10cm crosstrack error 

         (goal is 1cm/s)

(3) edit: gautoedit.py
    from gautoedit, for every screen do
	- mark seabed if necessary
	- additional manual editing if necessary
	- apply edits (creates/appends new a*.asc files with new flags)



(4) apply editing

   quick_adcp.py --steps2rerun apply_edit:navsteps:calib --proc_engine python --datatype uhdas --auto
	(if you don't want to sit and hit y for all questions, add "yes | " before the command (no quotes))

Small tweak and we're good.



(5) apply calibration

correct to third sig fig for amplitude; second for phase 
if both are positive values, enter a positive correction

quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_amplitude 1.00 --rotate_angle 0.063  --auto

Number of edited points:  34 out of  35
   amp   = 1.0000  + 0.0006 (t - 146.7)
   phase =   0.07  + 0.0592 (t - 146.7)
            median     mean      std
amplitude   0.9970   1.0000   0.0081
phase      -0.0005   0.0744   0.4648

delta-u    -0.5250  -0.0635   3.1929
delta-v    -0.5900  -0.3365   3.5197

Looks pretty pretty nice.
