usage:
Procedure:
(1) view hcorr*.png
(2) if there are gaps or if the tools above are useful, run "patch_hcorr_app.py"
from inside the sonar processing, "cal" or "rotate" directories
(3) edit gaps using the patch_hcorr App
This App:
- reads "ens_hcorr.asc" and plots components
- allows simple graphical editing of the file to
+ cut out chunks (interpolates through them)
+ trim outliers by
* using "cleaner" (removes spiks by using 2nd derivative)
* median filter cutoff (set filter length, threshold)
* box filter
- Edit button:
+ mask out points using standard selection tools (rectangle, polygon,...)
- Save button:
+ write new ascii files:
"newhcorr.asc" (for figures)
"newhcorr.ang" (apply to the database)
+ make figures showing new heading correction (newhcorr*.png)
+ stages "unrotate.tmp"
+ stages "rotate_fixed.tmp"
- Apply and Edit button:
+ run "rotate unrotate.tmp" to remove the original heading corrections
+ run "rotate rotate_fixed.tmp" to apply newhcorr.ang to the database
+ rerun the navigation steps using the following command:
cd ../.. #go back to the root sonar processing directory
quick_adcp.py --steps2rerun navsteps:calib --auto
NOTES:
(1) You must delete newhcorr* before you start
(2) "unrotate.tmp" resets the calibrations to
- phase correction 0.0
- scale factor 1.0
If you already applied any fixed phase or scale factor
you must apply them again.
optional arguments:
-h, --help show this help message and exit
--ens_hcorr_path [ENS_HCORR_PATH]
Path to ens_hcorr.asc file
--sonar [SONAR] Sonar name, ADCP+frequency+mode (see applicable), ex.:
os75nb, wh300
--yearbase [YEARBASE]
Database's year base, YYYY, ex.: 2018
--debug Switches on debug level logging and writes in
./debug.log
