Useful ec150fm data was only collected during part 2. PROCESSOR : J.Hummon --- final processing parameters from dbinfo.txt ---------- #this file was automatically generated.

Check visual oddities -------------------------- ### Run this: (to look for gaps in the cruise track) plot_nav.py nav/a*.gps ### Run this: (to look for gaps in the heading correction, examine the character of <...> the watertrack and bottom track calibration, etc figview.py ### Run this: (looking for missing heading correction values or missing positions) dataviewer.py # patch_hcorr.py is not required --------------------- ### 2. ADCP calibration --------------------- # Insufficient calibration data. # Use recommended values: # amp phase dx dy # ec150 1.003 -0.11 0 0 (posmv) quick_adcp.py --steps2rerun rotate:navsteps:calib --rotate_angle -0.11 --rotate_amplitude 1.003 --auto ------------------- ### 3. Editing points ------------------- ### Run this: (to go through the dataset and edit out bad values) dataviewer.py -e -------------------------------------------------- ### 4. Re-check heading correction and other figures ### Run this: (Is there anything strange with any of the figures?) figview.py -------------------------------------------------------------- ### 5. Check edited, calibrated dataset against original dataset -------------------------------------------------------------- ### Run this: (Has this corrected the problems in the original?) dataviewer.py -c . ../ec150fm.orig ### Run this to compare this sonar with another sonar (after both are finished) dataviewer.py -c ../os38nb . pretty good agreement where they overlap, but a small calibration disagreement ### Final cleanup: Because this is a new instrument, we did not realize ### the original depths were too deep by one bin. A specialized program ### was used to correct this ("depth_change_ec"). A log of this change ### is appended to the end of this file. ------------------------- ### 6.
