I first ran adcp_database maker with adjustments to the xducer calibration coefficients. Then gaps in heading existed, so I then used patch_hcorr.py to fix the heading data. Data below the bottom was removed, as well as small bits of data at the bottom of the sonar's range was removed. Editing and updating the heading correction improved the data during heading changes.
