Check visual oddities -------------------------- ### Run this: plot_nav.py nav/a*.gps There is ctd wire interference Removing scattering layer tails ### Run this: figview.py ### Run this: dataviewer.py lost heading when the cruise is just starting are just being restarted out of an eez Adjusted first points Post stop start seemed to work fine with the aglorithm ### Run this: cd cal/rotate patch_hcorr.py cd ../.. Adjusted first points Post stop start seemed to work fine with the aglorithm ### Run this: catwt.py **watertrack** ----------- Number of edited points: 156 out of 158 median mean std amplitude 1.0030 1.0037 0.0081 phase -0.1040 -0.1120 0.4245 ----------- ### Run this: catbt.py ### Run this: catxy.py **transducer-gps offset** ----------- guessing ADCP (dx=starboard, dy=fwd) meters from GPS positions from a_rb.agt calculation done at 2023/04/05 21:29:51 xducer_dx = -2.175559 xducer_dy = 2.372607 signal = 1367.947880 --------------------- ### 2. ADCP calibration --------------------- ### Run this: (look at the watertrack calibration residuals remaining) catwt.py **watertrack** ----------- Number of edited points: 156 out of 158 median mean std amplitude 1.0030 1.0039 0.0082 phase -0.1040 -0.1114 0.4244 ### Run this: catbt.py ### Run this: catxy.py **transducer-gps offset** ----------- guessing ADCP (dx=starboard, dy=fwd) meters from GPS positions from a_rb.agt calculation done at 2024/03/05 21:02:02 xducer_dx = -2.125457 xducer_dy = 2.438768 signal = 1367.947889 ----------- quick_adcp.py --steps2rerun rotate:navsteps:calib --rotate_amplitude 1.0030 --rotate_angle -0.1040 --xducer_dx -2 --xducer_dy 2 --auto ### Run this: catwt.py **watertrack** ----------- Number of edited points: 156 out of 158 median mean std amplitude 1.0000 1.0008 0.0081 phase -0.0060 -0.0093 0.4216 ----------- ### Run this: (look at the offset again) catxy.py **transducer-gps offset** ----------- guessing ADCP (dx=starboard, dy=fwd) meters from GPS positions from a_rb.agt calculation done at 2024/03/05 21:10:13 xducer_dx = -0.054603 xducer_dy = 0.378657 signal = 1367.947889 ----------- ------------------- ### 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 ### Run this: catwt.py ### Run this: catxy.py -------------------------------------------------- ### 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 . ../os75bb.orig ### Run this to compare this sonar with another sonar (after both are finished) dataviewer.py -c ../os75nb . Due to artifcates on the last day of the cruise we decided to run our uvship algorithm on the data. quick_adcp.py --steps2rerun navsteps:calib --refuv_source uvship --auto This looks better ------------------------- ### 6. Make plots and files ------------------------- ### Run this: quick_web.py --interactive ~5 day chunks with care for the data gap ### Run this to extract matlab files quick_adcp.py --steps2rerun matfiles --auto ### Run this to extract a netCDF file adcp_nc.py adcpdb contour/os75bb RB2301 os75bb --ship_name RON_BROWN ### Run this to look at the headers ncdump -h contour/os75bb.nc
