Gaps in heading correction required patch_hcorr.py to be run. Data below the bottom was removed, as well as small bits of data at the bottom of the sonar's range.

Check visual oddities ------------------------------------------------------------------------------ # I ran this to interpolate for missing heading correction fixes. cd cal/rotate patch_hcorr.py # I ran this: (to look for gaps in the cruise track) plot_nav.py nav/a*.gps figview.py dataviewer.py catwt.py catxy.py **transducer-gps offset** ----------- guessing ADCP (dx=starboard, dy=fwd) meters from GPS positions from a_ftoo.gps calculation done at 2023/12/15 01:56:31 xducer_dx = -4.299421 xducer_dy = 0.025098 signal = 668.470134 ----------- **watertrack** ----------- Number of edited points: 31 out of 31 median mean std amplitude 1.0040 1.0022 0.0053 phase -0.0900 -0.0218 0.2841 ----------- ------------------------------------------------------------------------------ ### 2. ADCP calibration ------------------------------------------------------------------------------ ### To apply the calibration adjustment I ran. quick_adcp.py --steps2rerun rotate:navsteps:calib --rotate_amplitude 1.003 --rotate_angle -0.1 --auto ------------------------------------------------------------------------------ ### 3. Editing points ------------------------------------------------------------------------------ # To go through the dataset and edit out bad values I ran. dataviewer.py -e # To recompute the calibration residuals I ran. quick_adcp.py --steps2rerun navsteps:calib --auto # I ended up removing most of the upper 25m. ------------------------------------------------------------------------------ ### 4. Check edited, calibrated dataset against original dataset ------------------------------------------------------------------------------ ### Run this: (Has this corrected the problems in the original?) dataviewer.py -c . ../ec150cw.orig ### Run this to compare this sonar with another sonar (after both are finished) dataviewer.py -c ../wh300. # Because I ended up removing most of the upper 25m for the ec150, I cannot # compare the surface differences. Overall there was a difference of # "extremes". That is, the wh300 has stronger u and v components. The overall # trends are similar and can the differences I believe can be accounted for # by differences in resolution. ### 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. ------------------------------------------------------------------------------ ### 5.
