ready for JASADCP
INSTRUMENT : os75
ACQUISITION :
PROGRAM : uhdas
PROCESSING: : python
LOGGING :
PARAMETERS : BT : bottom track mode (on or off)
SI : sampling interval or averaging period for ensemble (sec)
NB : number of bins
BL : bin length (m)
TD : transducer depth (m)
BK : blanking length (m)
HO : heading offset applied by DAS (deg)
HB : heading bias (deg)
CRPH : compensation for roll-pitch-heading, 1:on, 0:off)
yy/mm/dd hh:mm:ss BT SI NB BL TD BK HO HB CRPH
2010/03/07 17:38:49 off 300 60 16 5 8 66.90 0.00 0001
HEADING :
PRIMARY : phins
CALIBRATION : original heading alignment: 66.9
: need it to be 67.30 , so -0.4 calibration
: (consistent with watertrack)
: : tweak by -0.4
: amplitude: 1.00 amplitude, tweaked by 1.006
COMMENTS : no heading correction: phins was coming in the gyro port.
PROCESSOR : J.Hummon

adcptree.py os75nb --datatype uhdas --cruisename at15_63
(3) change directories to ADCP processing directory just created
cd os75nb
(4) create a quick_adcp.py control file
unix: this example is written as a bash "heredoc" for
cut-and-past ease, but you can create q_py.cnt with
an editor to have the parts between (or including)
the comments
cat << EOF > q_py.cnt
####----- begin q_py.cnt------------
## all lines after the first "#" sign are ignored
--yearbase 2010
--cruisename at15_63 # used to identify configuration files
# *must* match prefix of files in config dir
--update_gbin ## NOTE: You must remake gbins for python processing if
## - you are not sure
## - if parameters for averaging changed
## - various other reasons.
## ==> just do it, and put them somewhere else
## (see next argument)
--py_gbindirbase gbin # (will put them locally)
--configtype matlab ## python processing can read either type
--sonar os75nb
--dbname aship
--datatype uhdas
--ens_len 300
--ping_headcorr ## applies heading correction.
## settings found in config files
--proc_engine python ## use python to do calculations
--configtype python
--max_search_depth 500 ## do not look for the bottom in open ocean

(5) run quick_adcp.py:
quick_adcp.py --cntfile q_py.cnt --auto
----------
(6) (a) check calibration:heading correction device:
figview.py cal/rotate/*png
conclude: no action needed
(b) check calibration:
**watertrack**
------------
Number of edited points: 109 out of 113
amp = 1.0065 + 0.0002 (t - 88.8)
phase = -0.41 + 0.0012 (t - 88.8)
median mean std
amplitude 1.0060 1.0065 0.0088
phase -0.3700 -0.4051 0.4187
------------
**watertrack** (cal/watertrk/adcpcal.out)
-------------------
(7) edit "gautoedit" (go to "edit" directory with command line,
type "gautoedit.py"
# apply editing:
cd ..
quick_adcp.py --steps2rerun apply_edit:navsteps:calib --auto
# check editing -- looks OK
**watertrack**
------------
Number of edited points: 109 out of 111
amp = 1.0065 + 0.0002 (t - 88.8)
phase = -0.41 + 0.0011 (t - 88.8)
median mean std
amplitude 1.0060 1.0065 0.0088
phase -0.3700 -0.4058 0.4197
------------
dataviewer.py
- check calibrations again
EG. still need scale factor:
quick_adcp.py --steps2rerun rotate:apply_edit:navsteps:calib --rotate_amplitude 1.006 --rotate_angle -0.4 --auto
**watertrack**
------------
Number of edited points: 109 out of 111
amp = 1.0006 + 0.0002 (t - 88.8)
phase = -0.01 + 0.0009 (t - 88.8)
median mean std
amplitude 1.0000 1.0006 0.0087
phase 0.0300 -0.0056 0.4192
