(1) new processing directory


 adcptree.py  nb150  \

(2) make gbins

# need to update gbins

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

(5) editing; recalibration


Editing: can still see on-off station changes in V (amplitude)

Try again:


quick_adcp.py --yearbase 2007 --use_refsm --steps2rerun \
  rotate:navsteps:calib:matfiles  \
  --rotate_angle -.1 --rotate_amplitude .979 --auto
