I performed a dxdy calibration. Heading correction was determined from the first 8 cruises of 2023 and requires no further change. Data below the bottom was removed, as well as small bits of data at the the bottom of the sonars range was removed. Editing and updating the dxdy correction improved the data during heading changes.

Check visual oddities -------------------------------------------------------------------------------- # I ran this to look for gaps in the cruise track. plot_nav.py nav/a*.gps # I ran this to look for gaps in the heading correction. figview.py # I ran this looking for missing heading correction values or missing positions. dataviewer.py # Patch hcorr will not be needed.
