--------------------------------------------------------------

(1) new processing directory


 adcptree.py  nb150  \
  --datatype uhdas \
  --configbase KNOX14RR \
 --configpath /home/ipu1/uhdas_data_archive/revelle/KNOX14RR_legs/KNOX14RR/proc/nb150/config


edit config files; specifically, choose phins for heading


(2) make gbins

# need to update gbins


     nbcfg = get_uhdascfg('cfgpath', 'config',...
                              'cfgbase', 'KNOX14RR',...
                              'instname', 'nb150',...
                              'instclass', nb,...
                              'pingtype', 'nb', ...
                              'uhdas_dir', '../data');

  update_gbin(nbcfg,'whichones','all','logfpath','.','redo',1)

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

(5) editing; recalibration

tried heading correction with ashtech, but it didn't help much.
phins seems to do a reasonable job.



watertrack:
----------
Number of edited points: 167 out of 211
   amp   = 0.9985  + -0.0003 (t -  49.5)
   phase =  -0.04  + -0.0113 (t -  49.5)
            median     mean      std
amplitude   0.9990   0.9985   0.0079
phase       0.0730  -0.0407   0.7399


I think that's it.
