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

this is a linux machine; use little-endian database
(remove all other databases)


(0) remake all the plots

quick_mplplots.py --plots2run all --yearbase 2017

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

    figview.py cal/rotate/*png

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


(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)

delta-v    -0.7600  -0.3500   3.3497

(sometimes this will need amplitude and phase adjustment in later steps)
Looks GOOD


(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 sonar:

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


(5) apply calibration

quick_adcp.py --steps2rerun rotate:navsteps:calib:matfiles --proc_engine python --rotate_amplitude 1.002 --rotate_angle -0.040 --datatype uhdas --auto
