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 ### Run this: (to check watertrack calibration after patching hcorr) catwt.py **watertrack** ------------ Number of edited points: 14 out of 15 amp = 0.9999 + 0.0018 (t - 216.1) phase = -0.18 + -0.1753 (t - 216.1) median mean std amplitude 1.0035 0.9999 0.0095 phase -0.2865 -0.1799 0.5804 ------------ These are in rough agreement with the overall calibration values we settled on for the group of 10 cruises in 2023. ### Run this: (to check dxdy statistics calibration after patching hcorr) catxy.py There are insufficient points to use these for calibration --------------------- ### 2. ADCP calibration --------------------- quick_adcp.py --steps2rerun rotate:navsteps:calib --rotate_amplitude 1.003 --rotate_angle -0.1 --auto ------------------- ### 3. Editing points ------------------- ### Run this: (to go through the dataset and edit out bad values) dataviewer.py -e ### Run this: (to recompute the calibration residuals) quick_adcp.py --steps2rerun navsteps:calib --auto -------------------------------------------------- ### 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 ../ANOTHER_SONAR . FIXME : Was this done? ### 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.
